The main edifice of the ensemble is a hall-church with three naves,with arches disposed in a network,built between 1492 - 1516 on the place of another old church, in the late Gothic style,with elements from the Renaissance arhitecture at some portals.
Inside the church the late Gothic shrine, in the form of a triptych was realized in more stages between 1515-1524.
The pews are made between 1514-1523 by Reychmut from Sighisoara and are ones of the most valuable pews of this kind from Transylvania.
Unique in its way the door of the vestry built in 1515,is remarkable for its blocking system.
As a result of the earthquake in 1977 , restoration and consolidation works of the arches were done
