We will be in Split for one day on a cruise. What are the must see sites. I know about the old city and Diocletian's Palace.
The Cathedral of St. Dominus is a splendid church on the grounds of the Palace complex, with fabulous mosaics in the basement.
For sculpture, there’s the Ivan Meštrović Galkery museum, full of many of his works. Born in Croatia, he emigrated to the U.S. after World War II, and was interred back in Croatia after he died in 1962.
The suburb of Solin, just northeast of Split, has the Ancient Roman Ruins of Solana.
BTW, I also just posted a recommendation for a private guide to Pompeii, on your question from last month. Happy Travels!
We enjoyed our walk out to the marina and lunch at Restoran Adriatic. What a view!
