While exploring the maze of narrow streets, keep an eye out for Europe’s narrowest street. Pusti me proc, or Let Me Pass, is only wide enough for one person to pass at a time, hence its unusual name! Squeeze down this street and discover the unassuming Jupiter’s temple, built in the 3rd century AD – today it is the cathedral’s baptistery. Marvel at the ancient carvings of Roman gods, mismatched with the huge font in the centre of the temple, and Statue of St.John the Baptist, which replaced the statue of Jupiter.
