Diocletian's Palace (Croatian: Dioklecijanova palača, pronounced [diokletsijǎːnova pǎlatʃa]; Latin: Palatium Diocletiani) is an ancient Roman palace and fortress complex in Split, Croatia. It was built at the end of the third century AD by the Roman Emperor Diocletian as his retirement residence. About half of the complex was for Diocletian's personal use, with the rest housing the military garrison.
