In the center of Ulm stands the Münster, Germany's largest Gothic church after Cologne Cathedral. Started in 1377, its soaring spire was a work in progress that began in the 14th century and was finally completed in 1890 on the basis of a sketch left by Matthias Böblinger. The tallest church spire in the world at 162 meters — five meters taller than its counterpart in Cologne — it dominates the city skyline, and is particularly stunning when viewed from the banks of the nearby River Danube.
Interior highlights include its fine choir stalls built in 1469, as well as the narrow staircase inside the tower (it's tough going, but the wonderful views to the Alps make the hard work worth it). A series of organ recitals are held throughout the summer months. A rather more current take on church architecture can be seen in the St. John the Baptist Church, which was extensively remodeled in the modernist style in the 1920s.
