Belgrade has been invaded and occupied dozens of times over the centuries, a fact that's reflected in the mish-mash of architectural styles, from Ottoman and Art Nouveau to grim relics of the communist era.

The riverside town of Vidin is situated in the north west corner of Bulgaria, close to the border with Romania and Serbia. The architectural highlight is the magnificently well preserved Baba Vida fortress, and the town is also home to a mosque, a synagogue and several churches.
