Name for the square in front of the Saint Dominus Cathedral in the Old Town of Split. Peristyle as the central square of the Palace, housed in a section where several temples were built, was intended for Diocletianus. The sides are bordered by two rows of Corinthian columns interconnected by each other. The sides of the facade were decorated with two sphinces, one of which is still perfectly preserved on the square today. The front of the square is divided into two parts: the upper waters of the Vestibul, and the lower stairs in the magnificent palace basement. The facade leading to Vestibul was decorated with three statues, one of which was the Emperor Diocletian, the other god Jupiter, while the third remained unknown. Many tourists are attracted by one detail - an Egyptian sphinx located on the west side of the church. The sphinx is made of black granite,2.5 m long and about 1 m high. The Sphinx is a mythical creature with a lion's body and the head of the human or animal.
