The rock-hewn Sveta Petka Chapel is located in the town of Tran. A mystery surrounds of the history of this chapel as it is believed that St Petka was hiding in the cave after being fiercely prosecuted for her Christian beliefs during the 10-th century.

Later on the cave has been turned into a chapel. Thus the chapel is actually situated in a natural cave. In the cave one can see a stone in the form of a round bread with a hole in the middle and it is decorated with solar geometric motives similar to the decorations on the traditional Easter breads.

The cave ittself is situated amongst beautiful nature and the view over the town of Tran and the surrounding nature is worth experiencing.
