The Gothic Revival church in Ratajki was built in 1860 with red brick and boulders which were the most common construction material at the time. The temple is rectangular, with a pentagonal chancel at the rear wall. The front wall extends above the roof line on both ends of the building and is shaped like steps. The windows and alcoves on the front wall have the pointed arch shape. There is a closed cemetery by the church, as well as a number of majestic old trees.
