The Washington Monument is the centerpiece of intersecting Mount Vernon Place and Washington Place, an urban square in the Mount Vernon-Belvedere neighborhood north of downtown Baltimore, Maryland. It was the first major monument to honor George Washington (1732–1799).

The Monument, a colossal landmark column, was designed by American architect Robert Mills (1781–1855), who also designed the later Washington Monument on the National Mall in Washington, D.C. Construction began in 1815 on land donated by Colonel John Eager Howard (1752–1827), from his extensive "Belvidere" estate just north of Baltimore Town, and the masonry work was completed by 1829. The 178 foot, 8 inch doric column holds a ground-floor gallery offering digital exhibits about the construction of the Monument, the history of Mount Vernon and Washington Places neighborhood and of the life and accomplishments of General and President George Washington. Climbing the 227 steps to the top provides a view of the city from the historic neighborhood where it is located. Its neighbors and cultural institutions within a few blocks include the Peabody Institute, The Walters Art Museum, the Central Library of the Enoch Pratt Free Library, the Maryland Center for History and Culture with its Enoch Pratt Mansion, the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary (old Baltimore Cathedral), and the Baltimore School for the Arts (public high school).

The glorification of Washington began long before his death at his Mount Vernon estate, along the Potomac River in Virginia in December 1799. The old Confederation Congress (1781–1789 under Articles of Confederation and Perpetual Union) had first announced a desire for a sculpture in his honor in 1783 after the end of the War and of General Washington's resigning of his commission and after his death, revived the idea of a memorial. However, these expressions of honor in the national capital floundered and would not be realized for decades. A monument honoring Washington in Baltimore, then an up-and-coming rising town, the third largest in North America, was first proposed as early as 1807, and in 1809 a Board of Managers of private citizens formed to commission and fund the monument intended to be erected in the old former colonial-era Courthouse Square on North Calvert Street, between East Lexington and East Fayette Streets (today's location of the Battle Monument Square, constructed simultaneously 1815–1822). In 1810, the first lottery authorized by the General Assembly of Maryland, was held. In 1813, an architectural competition was announced with a $500 prize to design and build the Monument at a cost of $100,000. Mills's design was chosen in 1814, the architect having taken pains to demonstrate to the Board of Managers that he was the first native born American with architectural training. The cornerstone was laid with great ceremony on Independence Day, July 4, 1815.

Mills's competition-winning designs included rich ornamentation, six iron galleries (balconies) dividing the exterior shaft into seven sections with text and images on each level highlighting important moments in Washington's life. An interior spiral staircase led to the top, where surmounting the column Washington was depicted in a quadriga. Concerns over the expense of this design, as well as its projected height caused later changes in not only its design, but location. Residents of old Courthouse Square feared the tall column would fall on their houses in the event of some natural disaster, so a new location was found in Howard's Woods, north of the city, on the "Belvidere" estate and with a 200 square feet of surrounding land for future public squares/parks, which was donated by noted leading citizen, American Revolutionary War hero, Col. John Eager Howard, (1752–1827) of the famed "Maryland Line" regiment of the Continental Army.

By the time the Monument's cornerstone was laid in Howard's Woods in 1815, Mills had significantly simplified the original elaborate design as depicted in an account of the Fourth of July ceremony. The design of the completed column is very similar to the Colonne Vendôme in Paris, which ultimately derived from Trajan's Column in Rome and was adopted in this time of the increasing popularity of Neoclassicism in American architecture.

The dignified cornerstone ceremony was overseen by the Monument's Board of Managers. Board President and noted citizen, James Buchanan observed that the city of Baltimore had not only "the glory of being the first to erect a monument of gratitude to the father and benefactor of our country," but that it had a "peculiar propriety" in erecting "this first expression of national gratitude," because of its successful defense against the British Army and Royal Navy during the Battle of Baltimore the previous fall.

At the ceremony it was declared that the Monument was to stand as "memorial of the blessings and advantages that our country derived from the character of and conduct of that personage whose name it is to bear, and whose virtues it is to perpetuate." Following speeches, the cornerstone was laid by Levin Winder, then Governor of Maryland and head of the Maryland Freemasons, in a dignified masonic ceremony. The entire proceedings were printed in the local newspaper, picked up by newspapers in other major cities, and published in a souvenir booklet with illustrations.

Almost from the moment the cornerstone was laid, and particularly as the structure began to rise out of the ground (the first marble was laid in 1816), the Monument was a destination and an active memorial. In June 1817, during fifth President James Monroe's visit to the city, his itinerary included a visit to the Monument. Construction sites in the early nineteenth century were not what they are today, and during the building period it is clear the Monument was visited inside and out. As early as 1819 guests were leaving evidence of their visit in the Monument's subterranean vaults. By shortly after 1820 with the column proper largely complete with its integral interior staircase, visitors were already climbing to the top. New York City newspaper editor Nathaniel H. Carter visited in February 1823 and climbed to the top, escorted by a boy with a candle, to take in the views of the city.
