Take a tour of St. Dionys Cathedral in Germany - part of the World’s Greatest Attractions travel video series by GeoBeats. The granoise St. Dionys Cathedral stands in the heart of the southern city of Esslingen, Germany. This church is a combination of three structures which date to the 13th and 14th centuries, and were built up the foundation of an earlier 8th century church. The two towers were originally separate churches, now joined together by an elevated bridge.
