This is the State Reformed Church of Twijzelerheide in the Dutch province of Friesland. Because it is built on weak soil it has buttresses against the walls. To avoid heat loss during the winter months it has double windows. The whole building was recently restored. Because of the “Samen Op Weg” (together on our way) Movement, the State Reformed Churches and the Synodal Reformed Churches of the area have combined services in this church building.
