The Berkeley Building (also known as the Old John Hancock Building) is a 26-story, 495-foot (151 m) building located at 200 Berkeley Street, Boston, Massachusetts, USA. It is the second of the three John Hancock buildings built in Boston; it was succeeded by the John Hancock Tower. The building is known for the weather beacon at its summit, which displays distinctive light patterns as weather forecasts. The Berkeley Building is the 25th-tallest building in the city.
Key Information
History
[edit]The building, located in Boston's Back Bay, was designed by Boston's Cram and Ferguson and completed in 1947. The contractor was the city's Turner Construction, the building sheathed in Berea Sandstone from northeast Ohio.[1] From 1947 until 1964 it was the second-tallest building in the city, one foot (30 cm) shorter than the 496-foot (151 m) Custom House Tower, but a much larger building and a conspicuous landmark. The Prudential Tower, completed in 1964, dwarfed both. As of 2004[update], 17 buildings are taller, yet it remains an easily recognized Boston landmark, familiar to commuters crossing the Charles River. A drawing of this building served as a logo for the John Hancock Insurance company for many years.
In March 2003, the John Hancock Insurance company sold the Berkeley Building, along with the Stephen L. Brown building and the John Hancock Tower, to Beacon Capital Partners. In December 2006, the Berkeley and Brown buildings were reacquired by John Hancock. As of 2004[update] the John Hancock company refers to it as "The Berkeley Building," but in common parlance it is "the Old John Hancock Building."
Design and features
[edit]Observation Floor
[edit]In addition to regular offices, the top 26th floor also accommodated two observation areas looking out over the Boston skyline. Access was free to the public and a Reception and Information Desk was staffed during normal business hours.
Back Bay Events Center
[edit]It is also the home of the Back Bay Events Center: this two-part structure is the John Hancock Hall proper and the Dorothy Quincy Suite (a single room, capacity of approximately 900.) The Hall also contains a full box office and an 1100-seat auditorium. This is the annual site of the Massachusetts High School Drama Guild One-Act Festival's State Finals.
Weather beacon
[edit]It is topped by a weather beacon with red and blue lights, which use a code to present the local weather forecast,[2][3] using a popular rhyme as a mnemonic:
- Steady blue, clear view.
- Flashing blue, clouds due.
- Steady red, rain ahead.
- Flashing red, snow instead.[4]
During baseball season, flashing red means the Boston Red Sox game has been called off on account of weather.
The beacon was first lit on March 15, 1950 and was controlled using forecasts from a meteorological agency located on the 26th floor. It was kept lit until 1973 when it was shut off to set an example during an energy crisis which also temporarily shut off the famed Citgo sign in Kenmore Square. The beacon was re-lit in 1983 and has continued to display the weather forecast ever since.
In October 2004, the beacon flashed red and blue to commemorate the World Series victory of the Boston Red Sox. This was the first time the color scheme changed since the beacon was lit in 1950. A new line was added to the poem accordingly:
- Flashing Blue and Red, The Curse of the Bambino is dead!
The beacon again flashed red and blue when the Red Sox won the 2007 World Series, as well as when they won the 2013 World Series. However, it did not flash red and blue the night they clinched the 2018 World Series.[citation needed]

History
Construction and Early Years
The John Hancock Mutual Life Insurance Company commissioned the construction of a new headquarters building in Boston's Back Bay neighborhood during the post-World War II era to accommodate its growing operations.[5] The project was designed by the Boston-based architectural firm Cram and Ferguson, whose work reflected influences from the streamlined Art Deco style adapted to the modernist trends of the late 1940s.[5] Construction began in 1945 and progressed rapidly amid the postwar building boom, culminating in the building's completion in December 1947.[6] At 495 feet (151 meters) tall with 26 stories, the structure stood as Boston's second-tallest building upon opening, narrowly behind the 496-foot Custom House Tower and ahead of other prominent skyscrapers of the era.[2] This height underscored its prominence in the city's skyline during a period of limited high-rise development. The building's design prioritized functional office space, with limestone cladding and setbacks that evoked a sense of solidity and permanence suitable for an insurance company's headquarters.[1] Upon completion, the Berkeley Building—then known simply as the John Hancock Building—immediately housed the company's administrative offices, executive suites, and key operational departments, centralizing activities previously dispersed across older facilities.[6] It served as the primary hub for John Hancock's business for decades, symbolizing the company's stability and expansion in the postwar economy. In 1950, the installation of a weather beacon atop the tower added an early navigational and informational feature for the city.[2]Ownership and Name Changes
The Berkeley Building remained under the ownership of John Hancock Mutual Life Insurance Company from its opening in 1947 until March 2003, though the company relocated its headquarters to the John Hancock Tower in 1977. In March 2003, John Hancock sold the building as part of a portfolio that included the John Hancock Tower at 200 Clarendon Street and the Stephen L. Brown Building at 197 Clarendon Street to Beacon Capital Partners for $910 million.[7] During Beacon Capital Partners' ownership from 2003 to 2006, the firm shifted the building toward multi-tenant operations and invested in management improvements, including a $13 million capital plan to upgrade mechanical and building systems, which achieved annual operating cost savings of $2.7 million.[8] In December 2006, John Hancock Financial Services—a subsidiary of Manulife Financial—reacquired the Berkeley Building along with the Stephen L. Brown Building from Beacon Capital Partners.[9] In 2018, John Hancock relocated its U.S. headquarters from the Seaport District back to the Back Bay, with the Berkeley Building at 200 Berkeley Street serving as its primary headquarters location as of 2025.[10][11] After the John Hancock Tower opened in 1976, the building was commonly known as the "Old John Hancock Building" to differentiate it from the newer structure. It was officially renamed the Berkeley Building in 2003, aligning with its street address at 200 Berkeley Street.[12]Architecture
Design and Style
The Berkeley Building exemplifies late Art Deco architecture, constructed as a 26-story tower completed in 1947 that introduced significant height to Boston's Back Bay skyline.[5] Its design emphasizes sleek vertical lines through tiered setbacks that taper toward a shallow stepped pyramid at the summit, creating a sense of upward momentum with minimal ornamentation characteristic of the style's later phase.[5] The architectural firm Cram and Ferguson, known for blending traditional and modern elements, drew on 1930s skyscraper aesthetics—such as the emphasis on verticality and geometric massing—while adapting them to post-World War II sensibilities and Boston's longstanding regulatory height limits in the Back Bay, which had capped most structures at 125 feet until exceptions allowed taller developments.[1] The facade employs masonry cladding, including sandstone elements, to convey durability and modernity, with aluminum-framed spandrels and glass integrating curtain wall technology innovative for the era.[13][14] This design reflects regional variations in Art Deco, appearing more restrained than earlier Boston contemporaries like the nearby Statler Hotel (now Park Plaza Hotel), completed in 1927, where ornate geometric motifs dominate; the Berkeley Building's cleaner lines and reduced decoration highlight a shift toward postwar efficiency within New England's conservative building traditions.[15]Structural Details
The Berkeley Building is a steel-frame structure comprising 26 stories above ground and rising to a height of 495 feet (151 m).[16] The total floor area measures approximately 762,572 square feet, configured primarily for office use.[17] Completed in 1947, the building's foundation supports the load on Boston's characteristic blue clay soils, while the riveted steel beams in the frame were engineered to resist local wind loads, with minimal seismic design given the region's low earthquake risk. Riveting remained a standard connection method for steel skyscrapers into the 1940s before widespread adoption of welding.[18] The interior layout centers on a core housing elevators and stairs to optimize rentable office space on the floors, a common configuration for mid-20th-century high-rises. Mechanical systems included early post-war HVAC innovations, such as central air conditioning units adapted from Carrier Corporation's advancements in the 1930s and 1940s for commercial buildings.[19][18] Construction adhered to 1940s Boston building codes for fire-resistive structures (Type I under classifications similar to modern standards), with the steel frame fireproofed via concrete encasements on beams and columns to achieve required ratings for high-rise occupancy.[20]Notable Features
Weather Beacon
The Berkeley Building, completed in 1947, was topped with a weather beacon on March 15, 1950, when the John Hancock Mutual Life Insurance Company installed the feature as a public service to provide weather forecasts visible across the Boston area.[21][22] The beacon operates via a color-coded system using red and blue neon lights, following the mnemonic: steady blue for clear weather, flashing blue for clouds, steady red for rain, and flashing red for snow.[23][24] During baseball season, flashing red additionally signals the postponement of a Boston Red Sox home game due to weather.[25] The 65-foot-high tower features 288 neon lights—144 red and 144 blue—controlled manually from a basement operations center using simple switches for power, color, and flashing.[23][26] The beacon was turned off from 1973 to 1983 amid the national energy crisis, during which conservation efforts dimmed many such public displays, but it was restored in 1983 following public outcry from Bostonians who valued the landmark.[23][22] Beyond weather signaling, the beacon has marked celebratory moments, flashing both red and blue lights simultaneously to honor Boston Red Sox World Series victories in 2004, 2007, and 2013—the first such dual display in 2004 ending the team's 86-year championship drought.[25][4] It did not activate for the 2018 win.[22] The neon setup, originally powered by handmade tubes, remains a low-maintenance feature visible for miles on clear nights, serving as an enduring symbol of Boston's skyline. The beacon was offline from early 2024 until November for a major upgrade, including replacement with LED elements and automation via National Weather Service data, for improved efficiency.[4][3][27]Observation Floor
The observation areas of the Berkeley Building were located on the top (26th) floor, consisting of indoor spaces that offered panoramic views of Boston and its surroundings. The areas were equipped with interpretive signage identifying key landmarks, such as the Charles River, Fenway Park, and historic Back Bay structures, to enhance the educational experience for visitors. Since the building's completion in 1947, access to the observation areas was free to the public via a staffed reception on the ground level until at least the late 20th century; current public access is not available. In the mid-20th century, the observation floor served as a major public attraction for sightseeing, drawing crowds eager to experience elevated perspectives of the city when the 495-foot structure was the second-tallest building in Boston. Its popularity peaked during the 1950s and 1960s, with the areas accommodating group tours and individual visitors who appreciated its role in promoting civic pride and urban orientation; however, the arrival of taller skyscrapers, including the 749-foot Prudential Tower completed in 1964, began to diminish its unique vantage as the skyline evolved.[28][29]Back Bay Events Center
The Back Bay Events Center, housed within the historic Berkeley Building in Boston's Back Bay neighborhood, serves as a versatile multi-purpose venue for events and gatherings. It comprises the John Hancock Hall, a 1,100-seat theater equipped with a proscenium stage, refined acoustics, comfortable seating, and optimal sight lines, ideal for performances and large assemblies.[30][31] The adjacent Dorothy Quincy Suite functions as a spacious ballroom with its own stage and expansive dance floor, suitable for conferences, receptions, and social functions, complemented by multiple breakout and meeting rooms.[30][32] The center's facilities include state-of-the-art audiovisual equipment, Wi-Fi connectivity, professional staging, and in-house catering services, enabling seamless execution of diverse events such as corporate meetings, weddings, and live performances.[32][33] Stylish lighting designs and fine art from the deCordova Museum enhance the aesthetic appeal, while advanced sound systems ensure high-quality audio experiences.[32] The total event space spans approximately 26,000 square feet, providing flexibility for configurations ranging from intimate gatherings to larger productions.[30][34] Annually, the venue hosts the Massachusetts Educational Theater Guild (METG) High School Theater Festival Finals, showcasing top student productions from across the state in a three-day event that draws over 650 participants and audiences.[35][36] This longstanding programming underscores its role in supporting educational and cultural activities, alongside regular bookings for trade shows, seminars, and private celebrations.[32][37]Significance and Use
Role in Boston's Skyline
The Berkeley Building stands at 495 feet (151 meters), making it the 25th-tallest structure in Boston as of 2025 and a notable presence among the city's approximately 73 buildings exceeding 300 feet. Completed in 1947 as the second-tallest building in the city at the time, it quickly became an iconic mid-century marker in the Back Bay neighborhood, defining the area's vertical silhouette with its stepped Art Deco form before being overshadowed by the wave of taller towers constructed in the 1960s, including the 750-foot Prudential Tower.[38] Constructed in the immediate aftermath of World War II, the building embodied post-war optimism and economic resurgence in Boston, serving as a visual emblem of the city's aspirations for modern growth and corporate prominence. Its distinctive pyramid-like setbacks and weather beacon contributed to its role as a symbol of stability and innovation during a period of urban transformation.[5] While not officially landmarked, the Berkeley Building has been recognized in architectural historic surveys for its exemplary Art Deco design and contribution to Boston's prewar-to-postwar skyline evolution. Its pioneering height and style in the traditionally low-rise Back Bay helped pave the way for subsequent large-scale developments, such as the Prudential Center complex, by demonstrating the feasibility and aesthetic integration of high-rises in the neighborhood.[5] From the 1950s through the 1970s, the building featured prominently in skyline photographs and media representations of Boston, often capturing its beacon-lit crown against the evolving cityscape and underscoring its enduring visual impact before the dominance of newer supertalls.[39][40]Current Tenants and Operations
The Berkeley Building at 200 Berkeley Street in Boston operates as a mixed-use Class A office tower, accommodating corporate tenants alongside event spaces such as the Back Bay Events Center. Owned by John Hancock Financial Services—a subsidiary of Manulife Financial—since its reacquisition in December 2006, the property spans 762,572 square feet and supports a range of professional activities in the Back Bay neighborhood.[41][42][43] As of 2025, major tenants include Deloitte, the primary occupant leasing extensive space on multiple floors for consulting operations; John Hancock Funds LLC and John Hancock Life Insurance Co., which house key divisions including headquarters functions; and WeWork, providing flexible coworking and office solutions. Smaller firms in finance, such as RA Capital Management, and consulting occupy additional suites, contributing to a diverse tenant mix focused on professional services. The building features on-site amenities like high-end lobbies, panoramic views, and proximity to public transit, facilitating daily operations for approximately 29 identified tenants.[44][45] Sustainability efforts define the building's modern operations, with LEED Gold certification achieved in 2013 following post-2010 upgrades such as LED lighting installations and energy-efficient HVAC systems, reducing environmental impact while maintaining operational efficiency. These enhancements align with broader green building standards, emphasizing reduced energy consumption and improved indoor environmental quality.[46][43] No major structural renovations have been reported by late 2025, though ongoing management supports adaptive reuse amid market shifts. Vacancy rates at the property mirror Boston's post-COVID office recovery, with downtown rates declining to 26.1% in Q3 2025 amid increased leasing activity and stabilized rents around $47 per square foot.[47][48]References
