History+
Around 1250, the Mönchskirche was erected on the last available plot of land in Salzwedel's Old Town as a monastery church for the Franciscan Order. In 1345, the building underwent its first expansion with the addition of a vaulted choir and a southern aisle, with both the main and side naves also being vaulted. Between 1435 and 1500, the choir, main nave, and aisle were further enlarged, and a hall rood screen was installed. After the Reformation, the monastery became property of the city of Salzwedel, and the last monk died in 1552. The adjacent cloister was subsequently used as a Latin school. In the 16th century, the church received furnishings, including an altar from the workshop of Lucas Cranach the Younger in 1582.
