The church in Sątoczno was erected after the middle of the fourteenth century in a settlement established by the Teutonic Order. At the end of the 14th century and at the beginning of the 15th century, the chancel was added together with the sacristy, while in the second half of the 15th century and at the beginning of the 16th century, the tower was raised twice. In the 18th century, the Eulenburg family burial chapel was built. In the years 1839-1842, the nave was restored and the furnishings were replaced with classicist ones.
The church is orientated towards the sides of the world, made of bricks on a stone foundation, one-nave with a narrower and lower, three-side ended chancel. A 32-meter high tower is added to the west. The sacristy was located on the north side. The church is covered with a stellar, eight-arm vault.
