Sederholm House (or Sederholmin Talo) dates from 1757 and was the house of Helsinki's then-richest merchant, Johan Sederholm. A two-story stone building with a mustard-colored roof, it was the most luxurious house in the city. Business was done on the ground floor, with storage cellars below, and the family lived in the apartments on the floor above. Apart from the windows, which were enlarged in 1866, the house is as it was when built.
These days Sederholm House is part of the Helsinki City Museum which traces the history of the city. The historic Sederholm House is used for special exhibitions. The museum has a number of other sites also including the main location at Sofiankatu 4, the Tram Museum, the Power Station Museum, the School Museum, Hakasalmi Villa, the Burgher's House and the Worker Housing Museum. Each hosts exhibitions and together they form an excellent picture of life in Helsinki over the centuries.
