The entire area is a UNESCO World Heritage Site.
The peristyle is a monumental courtyard, which was formed on the northern entry point to Diocletian's imperial apartments. Now it is the heart of the palace, which is still very lively with tourists of course, but there is also a bar where people come to enjoy drinks, a bank, and tourist information desk. The peristyle used to offer access to the mausoleum of Diocletian, which is now the cathedral Sv Domnio of Split, and three temples on the west. Two of them were destroyed, the third is now a baptistery. The door through which you could enter this part of the palace was the most magnificent, the golden door.
