This place is also a must. Amazing little walled in city, right outside of Split. We spent the rest of the day slowing walking around, exploring the old town. Again, you could spend ½ a day just walking around and taking in the sites.
Missed: The Kamerlengo Fortress—this was closed when we went to go check it out and I think its something that probably can be missed. But, if you have time, it should be checked out
