Rotunda of Saints Peter and Paul, Romanesque rotunda in Starý Plzenec, Czech Republic

The Rotunda of Saints Peter and Paul is a small round church with a cylindrical interior space and a hemispherical vaulted apse positioned toward the east. The building displays typical Romanesque features with its solid stone structure and simple, functional design.

The rotunda was built in the western outer bailey of the early medieval Hůrka hillfort, first mentioned in 976 and the main seat of the Bohemian princes in western Bohemia, which bore the name Plzeň until the late 13th century. Construction is usually placed at the end of the 10th century, though newer research suggests the 12th century. After the centre moved to the new Plzeň the building decayed and collapsed in the 15th century; it was restored in the 16th century and properly reconstructed only in the 20th.
