Felsenkirche, Germany

 Felsenkirche, Germany. This church was built into a natural niche in the rocks above Oberstein, western Germany, in 1482-1484. It can only be entered through a tunnel ploughed into the rock, and it contains various liturgical objects, including an agate cross from Brazil, a rock crystal crucifix, and late Gothic glass windows – although these were damaged by falling rocks in the 18th century. A viewing platform was opened in 2003.
