Stiklestad Church was built at the site of the Battle of Stiklestad and completed in 1180. During the battle in 1030, St. Olaf received three severe wounds—in the knee, in the neck, and the final mortal blow through the heart—and died leaning against a large stone. The church building is assumed to have been erected on the exact spot where St. Olaf was killed during that battle and that stone is supposedly still inside the altar of the church. The church was designed by Archbishop Øystein Erlendsson.
References:The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
