I really enjoyed my stay in Split, not only for the obvious reason of finally getting to see the only Roman Emperor's palace still existing, but also for its very pleasant Mediterranean ambience and beautiful seaside setting - the Riva promenade especially. Diocletian's Palace is, of course, the major attraction. Covering the entire Old Town of Split, it features many historic monuments, including the Cathedral which was built over Diocletian's mausoleum. I found the underground passages to be the most interesting part. On the downside, the city was totally crowded with tourists, because it is quite a popular cruise port, so visits should be timed to the mornings and evenings. Split also makes a great base for trips to other WH sites, including Trogir, Hvar and Sibenik, but also to places such as Mostar, Dubrovnik, and the Plitvice Lakes.
