Here are some of Split's best sights:

Diocletian's Palace
Obviously, the most important sight is Roman emperor Diocletian's Palace. Get a locally published guide in English which describes this monument in great detail. Do not miss the Peristyle which is the main open space in the palace and is surrounded by a colonnade of six columns to the eastern and western sides and an arch, decorated with garlands, in the centre.

Cathedral of St Domnius (Katedrala Sveti Duje in Croatian)
On the eastern side of the Peristyle is this cathedral. Originally built - at the same time as the palace - as a mausoleum for Emperor Diocletion (who died in 313 AD), his remains vanished a few centuries later. In the 7th century, those who hadfled nearby Salona after it was attacked turned the mausoleum into a cathedral - and placed in it the bones of their Bishop, Domnius, whose execution had been ordered by Diocletian himself.

People's Square (Narodni trg in Croatian)
On the western side of the palace is the Narodni trg on which is the old town hall, which was built in the 15th century. The town hall houses an ethnographic museum (worth visiting) which was established in 1910. nearby is a city museum.

Statue of Gregory of Nin (Grgur Ninski in Croatian)
One of the most visited sights in Split is this remarkable statue by Ivan Mestrovic. Grgur Ninski was a Croatian religious leader from the 10th century. The big toe on the statue's left foot is shiny gold, having been rubbed by many people over the years - rubbing it is said to bring good luck.

Mestrovic Gallery
The famous Croatian sculptor Ivan Mestrovic designed this villa, which was completed in 1939, to use as his summer residence. The gallery was opened in 1952 and houses over 200 of Mestrovic's works.

Museums
Museums in Split include the Maritime Museum; the Museum of Croatian Archaeological Monuments; and the Museum of Croatia.
