The late romanesque rotunda in Stronia was built in the second half of the 13th century. It served as a rural parish church. In the 14th century the vestry was added to it from the north. In the sixteenth century the temple was taken over by Protestants, who raised the walls by 1 meter, and pierced the window openings in the nave and apse and demolished the original hemispherical vault in apse. In the seventeenth century a funeral chapel was added to the sacristy. Finally, around the middle of the nineteenth century a tower was built over the sacristy, which was raised at the turn of the 19th and 20th centuries.
The rotunda was built of glacial erratics and swamp ore. It consists of a circular nave and a horseshoe apse from the east and a quadrangular tower from the north. Originally, the building was lower and towerless. To the interior leads, southern, pointed portal, pointed are also windows in the apse.
