The gothic church in Szestno was built in the second half of the 15th century by the Teutonic Order. According to the preserved informations, in the second half of the 16th century the church fell into disrepair and at the turn of the 16th and 17th centuries a thorough renovation was undertaken. But soon the temple was destroyed by a fire in 1618. Its appearance is the result of reconstruction, which was finally completed in 1639 with the tower’s elevation and roofing. Numerous changes took place then in the form and design of the building.
It is an orientated temple, aisleless with a tower on the west side. The building was estabilished on a glacial erratic stones foundation combined with lime mortar and erected from bricks, with the exception of the lowest storey of the tower and walls of the annex on the north side, which were built of field stones and bricks. On the east side there is a sacristy, and from the north a porch. Corners of the nave, except for the contact with the tower on the south side, support the massive buttresses. The church has a crest top decorated with seven semi-circular blendes. The five-storey tower is decorated with strips of blendes, windows of varied shapes and a hip roof covered with tiles. It is believed that the church could have another nave or triple-span gallery opened to the nave, as evidenced by the walled arcades in the south wall.
The interior of the nave was covered with a wooden ceiling, where are polychromes imitating coffer from the first half of the 17th century. From the same period come wooden, painted matroneum running along the north and west walls of the church.
