Peristyle has allways been the heart of the Palace and the city since it’s by far most important and historiclly rather old imperial square. Some things were demolished, some altered, some holes were made; things were patched and built as such strained circumstances allowed. But, no matter time and centuries that has past it is still unique antique place where you can stamble upon an unusual coexistance of sphinxes, sarcophagi, early Christian crosses, medieval tombs, roman temples…etc.

A monumental court, called the Perystile, formed the northern access to the imperial apartments. It also gave access to Diocletian’s Mausoleum on the east (now the St. Dominus cathedral of Split), and to three temples on the west (two which are now lost, whilst the third was, similary to masoulem, transformed into a baptistery).

The northern half of the palace, which was divided in two parts by the main longitudinal street (cardo) leading from the North Gate to the Perystile, is less well preserved. It is usually supposed that each of these parts formed a large residential complex, housing soldiers, servants, and possibly some other facilities. Both parts were apparently surrounded on all sides by streets. Leading to perimeter walls there were rectangular buildings, possibly storage magazines.
