We can find five axes of symmetry on the exterior church facade. The corner towers ovelap the rest of the church and their square floor plan changes in last floor into the rounded.

The risalit it the dominant part of the composition. In the centre of composition is the octogonal dome above the crossing of interior space.

Facade is decorated by stucco ornaments. The windows are boutifully framed. The half-circle stairs create the entrance of church. Original baroque (and renewed) portal gate are coverd by decorative ironwork.

South frontage is decorated by statues by Antoním Braun (1735).
