The tripto catalogue lists 105 churches and monasteries – Gothic cathedrals, Romanesque imperial cathedrals, Baroque pilgrimage churches and medieval abbeys. More than half of them are free to enter.
Cologne Cathedral by the main station, with its 157-metre towers and the Shrine of the Three Kings, is a UNESCO World Heritage Site; since July 2026 a visit costs €12, while entry for prayer through the north portal remains free. The Frauenkirche in Dresden, destroyed in 1945 and reconsecrated in 2005, is free to visit; only the dome climb charges. Aachen Cathedral, with Charlemagne's Palatine Chapel, was Germany's first UNESCO World Heritage Site. Ulm Minster has the tallest church spire in the country at 161.53 metres. The Wieskirche in the Pfaffenwinkel is a Rococo masterpiece by the Zimmermann brothers, and Maulbronn Monastery is considered the best-preserved medieval monastery north of the Alps.
Most churches and monasteries in the catalogue are in Bavaria (over a dozen), Baden-Württemberg and North Rhine-Westphalia (about 10 each). Munich and Cologne have three each.
In practice: a visit usually takes one to two hours. The church itself is often free, while towers, crypts and treasuries charge – for example €7.50 for the south tower of Munich's Frauenkirche or €8 for the Michel tower in Hamburg. Sightseeing is not possible during services. With children, tower climbs are the highlight, for example in Ulm, Dresden and Frankfurt Cathedral.
