Ojamo Manor is named in the written sources for the first time in 1384. The significance of the manor house grew during the 16th century when iron ore was found from its grounds. The first findings are dated between 1528 and 1540.[3][4]
The King of Sweden,Gustav Vasa, gaveErik Fleming, the owner ofSuitia Manor inSiuntio, a permission to mine iron ore from the grounds of Ojamo Manor in 1542. From Ojamo the iron was transported to Siuntio to be refined inSuitia Ironworks. The iron mine in Ojamo is the oldest known iron mine in Finland. Attempts to mine iron ore from the grounds of Ojamo were done even during the 19th century. However, the mining operations ceased for the last time in 1862.[5][4]
The current main building of Ojamo Manor was built using timber in 1850 bylieutenant colonel Dimitri Swertschkoff. Ojamo Manor represents richly decorated Russianempire style. The building has one floor and a centrally positioned tower, which is a later addition. The decorations on the window frames resembleKarelian building style.[3]
Ojamo Manor is surrounded by a park. The southern part of the park has a maple alleyway, which leads to the grave of lieutenant colonel Swertschkoff. Other points of interest in the park area include several large mine openings on the ground, some of which are filled with water.[3]
