It is a single nave Baroque building with a set off polygonal Gothic presbytery, on the northern side there is a massive prism Renaissance tower and on the southern side there is a vestry. A flèche is situated on top of the roof. The tower clock was made by the Prague clockmaker L. Hainz in 1929. It is a massive machine with a sectioned cast iron frame, bronze wheels and steel shafts.
