Tammisalo

Tammisalo (Swedish: Tammelund) is a neighbourhood (number 44) and island in the eastern part of Helsinki, Finland.^[1] As of 2024, Tammisalo has a population of 2,331 and an area of 0.74 square kilometres (0.29 square miles).^[2][3] 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.^[2]

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.^[2]

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.^[2] The Finnish name Tammisalo was adopted in the 1950 city plan; the Swedish name Tammelund (originally Tammerlund) dates to the late 18th century.^[2]

A notable building in the low-rise suburb is the five-storey Tammelund house, designed by architect Antti Rantanen in 1935. With over 100 windows, it has been called a "miniature skyscraper".^[2] Tammisalo also has terraced housing designed by modernist architect Timo Penttilä in 1966.^[3]
