The Temple of Jupiter in Split (Croatian: Jupiterov hram) is a temple in Diocletian’s Palace that is dedicated to the Roman god of sky and thunder, Jupiter. It can be accessed from the Peristyle. It was built alongside the palace itself between 295 and 305 AD.
Around the 7th century, it was turned into a Baptistery of St. John the Baptist, and a crypt dedicated to St. Thomas was built at the same time. The area around the temple entrance is decorated with reliefs depicting Roman gods and various heroes. The temple doors are also richly decorated.
Inside the temple, you will find a baptismal font, two sarcophaguses containing the remains of the Archbishops of Split, a bronze statue of St. John the Baptist made by Ivan Meštrović and another sarcophagus in front of the temple.
The Temple of Jupiter lies on an elevated podium, and a part of it forms the Street Let me pass, together with a restaurant that’s across the street. In front of the temple, you can find a headless sphinx.
