The eastern baroque country church stands on the eastern outskirts of Oberbrunn. The sandstone building has a single-tower facade with a roof turret. There is a central risalit below the entrance portal with a cartouche with the crowned coat of arms of the Prince Bishop Johann Philipp Anton von und zu Franckenstein. Above that is the belfry, not in the slated lantern, which has an octagonal floor plan, but in the gable area.[1]
The recessed chancel with a three-eighth note has a straight front wall, behind which is the sacristy, and rounded, recessed sloping walls. There is a tall rectangular window in each of the two side walls. A flat plaster ceiling with a profiled cornice and a triangle with the eye of God spans the chancel. A round choir arch connects the choir with the nave.[2]
A gallery axis and two window axes structure the nave with its hall, which is lit by four large windows. The corners are rounded. Two spiral staircases provide access to the wooden organ gallery. The pitched roof of the nave is covered with plain tiles.
