Ulm Minster (German: Ulmer Münster, literally: minster) is a Lutheran church located in Ulm, Germany. Although sometimes referred to as Ulm Cathedral because of its great size, the church is not a cathedral as it has never been the seat of a bishop.
Ulm Minster, like Cologne Cathedral (Kölner Dom), was begun in the Gothic era and not completed until the late 19th century. It is the tallest church in the world, and the 4th tallest structure built before the 20th century, with a steeple measuring 161.5 metres (530 ft) and containing 768 steps. From the top level at 143 m (469 ft) there is a panoramic view of Ulm in Baden-Württemberg and Neu-Ulm in Bavaria and, in clear weather, a vista of the Alps from Säntis to the Zugspitze. The final stairwell to the top (known as the third Gallery) is a tall, spiraling staircase that has barely enough room for one person.
