Mostar
Mostar has historically been a culturally and ethnically diverse country. Mostar's most famous and significant site is its old bridge, called Stari Most, which crosses the Neretva river. The bridge was originally constructed by the Turks in 1566, but was destroyed during the civil war in 1993. It was later rebuilt as a symbol of recovery in 2004. The rebuilt bridge can be seen today, and is surrounded on both sides of the river by the beautiful old town.
Mostar is a beautiful town set amid the mountains with the Neretva river flowing through it. There are some museums and interesting sites around town, but the true appeal is the old bridge and the town itself. You can pass much time just wandering through town and poking your head in some shops. The locals are quite friendly and eager to greet you as well.
