The Bruks Church in Österbybruk, built in 1735, is part of the manor complex, and is oriented north-south. The church is built in the late Carolingian style with farmhouse style roof and oval gables. The roof is tiled with shingle and tarred black. The outer walls are plastered and then coated with iron vitriol. Originally the church did not have any west facing windows, having only four east facing windows looking out towards the courtyard. - The church entrance is on the north side. The door frames are made from red marble and on the grey painted double doors are mirrors that are very robust. - On the south side in the direction of the manor house, there was once a door that has now been built over. When the manor house was occupied, this was the door that the nobility used.
