Saaristokatu is one of Raahe’s old seamen’s residential streets; most of the houses were built during the first half of the 19th century. Originally the houses had 1 or 2 rooms. They have gradually been extended. The houses in the street have generally been well looked after and inhabited. Fortunately the house at Saaristokatu 4 has still been preserved. It gives Saaristokatu a special charm and is the only house in Old Raahe which has its gable facing the street.

At the corner of Saaristokatu and Kauppakatu, at Kauppakatu 10, there is the Ruohonen house, which by Raahe standards is a typical small classisistic wooden house with its symmetrical window partition, six-paned windows, wide horizontal boarding, corner rustication, impressive eaves, and tiled roofing as well. The house has a long row of outbuildings well looked after, by the street The main building is on a high stone base, and when we bear in mind that the street level has been raised several dozen centimetres in connection with water, sewerage, and paving work, we get a good idea of how high up the houses were usually built in the 19th century.

The houses at this street corner all represent wood construction of the first hald of the 19th century, which in Raahe was characterized by balanced dimensions, symmetry of neo-classicism and modest embellishment.

Saaristokatu 7 is one of the new houses fitted in the wooden town environment. It replaced the former dilapidated semidetached house. The Åkerblom house and its yard designed by Architect Heli Kittilä continues the Old Raahe wood-building tradition in a modern way.

A new dwelling house fit in the old environment has been built at the corner of Saaristonkatu and Kirkkokatu replacing the former Latomaa shop.
