Diocletian's Palace

This massive stone building used to be a residence for the Roman emperor Diocletian. Although it was built over 1500 years ago, most of the structure is remarkably intact, and the imposing walls of the palace are one of the first features one notices when arriving at Split via ferry.

The inside of the palace is a cavernous space filled with souvenir shops and vendors hawking their wares, but there are also a few "exhibits" worth visiting. Most notable among these are the cellars, a vast expanse of large, cold stone rooms underneath the palace. The rooms are empty save for a few archeological exhibits, but are worth exploring anyway just to get a feel for the architecture. There are informational signs describing the palace in English, but they begin to repeat themselves after a while and are a bit difficult to follow, so it might be worthwhile to research information on the palace beforehand if you want to get the most out of your visit.
