A central nave with a porch on the south and a later hexagonal chancel with a sacristy added to it. A tower on the west. Built of fieldstone and brick. The main building, including the windows and walls, is mostly of fieldstone with fragments of brick. The main building and the chancel have buttresses. The tower is built of stone at the bottom, and its upper two storeys of brick. In 1700 the tower was damaged by lightning. A simple pointed-arch entrance leads into the central nave. The nave originally had stone vaults, later a cross-vaulted wooden ceiling. Altar of 1696. Pulpit of 1697. Organ of 1720. The church had four bells.
During the Second World War, when the German 4th Army was routed, fierce fighting took place in this area, and the church in Bladiau suffered heavily; the tower was hit especially hard.

The shattered church stood until the end of the 1970s. As late as 1975 the damaged tower of the church in Heiligenbeil (Mamonovo) could be clearly seen from its tower. Then the church was blown up and dismantled. Only the wall that had surrounded the cemetery and the church remained. In 1993 a simple wooden cross was erected on the site of the church.
