The church in Sątoczno was erected in 1326-1328 on the site of a settlement founded by the Teutonic Order. It was burned during the invasion of Lithuanians in 1347. The temple was rebuilt and at the turn of the 14th and in 15th centurie a chancel was built.
The church is orientated to the sides of the world, built from brick on a stone foundation. It has one nave with a larger and lower, three-side ended chancel. On the west side is a 32 meter high tower. The sacristy is on the north side, and from the south is the porch with former Eulenburg burial chapel. The church is covered with an apparent, timber stellar vault from the nineteenth century.
