Bulgaria has a good number of large natural bridges. Bozijat Most (God's Bridge) is so called because locals didn't know how it was formed. It is situated at the small village of Liljace, 12 km (7.5 miles) north of Vraca. There are ruins of an ancient castle alongside the top of the bridge. There appear to be two natural bridges; the photograph is of the second bridge. It is reported to be 83 feet wide and 66 ft high. Photo by Ray Millar.
