 Alfieri worked again in this church in the period 1720–1725, as well as the sculptor Giovanni Antonio Canevale.However, the church has retained some of its Gothic origins, such as pointed arches in the windows.The walls are decorated with rows of numerous armorial bearings of the Order of Teutonic Knights and several commemorative stones, such as the tombstone of Count Siegfried Sarau with relief work by Giovanni Stanetti and of bailiff Jobst von Wetzhausen (1524) by Loy Hering.
