Nin Cathedral

Nin Catheral is a cathedral in Nin, Croatia. It is probably the smallest cathedral ever built. It was built around 800, and probably was the seat of the local bishop at the time. The small cathedral was built on the area of a former Roman basilica, destroyed during the barbarian invasions of Dalmatia in the VI century. It measures 7.8 metres (26 ft) by 7.6 metres (25 ft) by 8.2 metres (27 ft) inside.
