It was built around the year 1300 as a church of the Cistercian monastery (in Koszalin from 1278 to the middle of the XVI century). It was significantly damaged during a fire in the city in 1718. In the years 1818-1819, it was subjected to major repairs; it also received new equipment (organs – 1863). In 1953 the church was passed to the Polish Autocephalic Orthodox Church and now fulfils its sacred functions.

The position of the executioner in medieval Koszalin had functioned since 1464. The executions were conducted on the so called „Hangman’s Hill” or on the municipal market. The last time the executioner fulfilled his duty for the city was in 1893, but he lived in the tenement house until the 30’s of the XX century.
