I previously did a fun fact on Croatia but wanted to add a second one just because Croatia is on my top 10 list of places to visit.
Did You Know that the Best Preserved Roman Palace in the World is in Split, Croatia?
It is the Palace of Diocletian and was build in A.D. 295. The Roman Emperor, Diocletian, had this palace built in preparation for his retirement and because he was originally from Dalmatia.
This is from Joseph Rosendo's Travelscope "Cruising the Mediterranean".
