Pula Amphitheater: Smaller than Rome's coliseum but in much better shape, the amphitheater is a lot more accessible to tourists. Don't miss the newly restored underground chambers and their exhibits featuring Istrian history. And if you happen to be in town when a concert is scheduled there, try to get a ticket no matter who is headlining.
Salona (Solin): The grandeur that was Rome is still evident in the crumbling buildings and foundations that grace this former outpost of the empire. It isn't difficult to imagine what Salona looked like in its prime, but it is tough to imagine why this magnificent city was left to sink into the Earth for a couple of centuries. Do not approach without sturdy walking shoes, sunscreen, and a full water bottle.
Diocletian's Palace (Split): It isn't what you think of when you hear the word "palace." First, Diocletian built his estate on a scale so grand it was converted into a city after he died. And second, the city's landscape has been tinkered with so much during the last 15 centuries that the character of the original complex has been all but obliterated. However, what remains of the palace and what has been built on its footprint is now Split's Old Town, and if you walk around it, through it, and under it enough, you'll begin to understand Diocletian's enormous ego.
