The Church of Saint Mary in Berc is built of large granite blocks. A contrast in construction is noticeable between the bell tower, with its regular masonry, and the rest of the building, which features a cross-vaulted pattern. The entrance is through a portal on the south side, surmounted by the spire erected in 1875, as indicated by the date engraved in the stone. A red Virgin in Majesty overlooks the portal in a niche with light-colored plaster walls. Inside, the church has a single nave with a pointed arch vault and two projecting side chapels. The walls are covered in light-colored plaster, with only the supporting columns and the arches of the side chapel vaults, which are made of granite, standing out. The two chapels house altarpieces depicting Mary on the south side and Christ on the north. On the road opposite the church stands a beautiful monolithic granite wayside cross. It depicts Christ on the cross. The date 1816 is engraved in a cartouche on the shaft.
