Tammisalo
Tammisalo (Swedish: Tammelund) is a neighbourhood (number 44) and island in the eastern part of Helsinki, Finland. As of 2024[update], Tammisalo has a population of 2,331 and an area of 0.74 square kilometres (0.29 square miles). The neighbouring districts are Herttoniemi, Roihuvuori, and Laajasalo. Tammisalo is separated from Roihuvuori by Tammisalo canal and from Laajasalo by Laajasalo canal. The surrounding waters include the bays of Porolahti, Tiiliruukinlahti, Jatasalmi, and Strömsinlahti.
Tammisalo was originally part of Laajasalo island. A strait at the site of the present Tammisalo canal separated it from the mainland, but it silted up during the 18th century. The Laajasalo canal was later cut through the isthmus connecting Tammisalo to the rest of Laajasalo in the late 19th century. A City of Helsinki area plan dates the canal through the isthmus to 1873–1875.
The area was separated from Herttoniemi manor in 1888. During the 19th century it was largely rural, used as a summer retreat. Plots began to be subdivided in the 1920s, and Tammisalo developed into a residential suburb in the late 1950s and early 1960s, when the old gravel roads were widened and paved. The Finnish name Tammisalo was adopted in the 1950 city plan; the Swedish name Tammelund (originally Tammerlund) dates to the late 18th century.
From the 1880s to the 1930s, Tammisalo was a villa area for Helsinki's well-to-do, of which few buildings survive. The most notable is Villa Edeshem at Jatasalmentie 11, built in 1898 to designs by Theodor Höijer for Nokia founder Fredrik Idestam as a seaside home. After Tammisalo was incorporated into Helsinki in 1946 it received its first town plan, designed by Birger Brunila in 1951. Its busiest building period was 1955–1975, during which Tammisalo Church (architect Lauri Silvennoinen, 1966) and the adjoining square formed the neighbourhood's civic centre.
Tammisalo is mainly a low-rise residential area. In Helsinki's 2002 master plan it was designated for detached-house housing, while its central blocks were marked for apartment housing and commercial or office construction. Its green areas are small and lie mostly along the shoreline.
The Porolahti canal, an early-18th-century sailing route, later became overgrown and was reopened in 2001, with the green areas on both sides of the canal mouth restored. The Laajasalo, or Degerö, canal and its 1874 bridge are identified in the plan as a culturally significant site.
A notable building in the low-rise suburb is the five-storey Tammelund house (As. Oy Tammelund), designed by architect Antti Rantanen in 1935. With over 100 windows, it has been called a "miniature skyscraper". Built by Edvard Alestalo, it was completed in 1938. Tammisalo also has terraced housing designed by modernist architect Timo Penttilä in 1966.
