St. Lamberti in Münster, Westphalia, was the market and civic church, a counter-foundation to the overpowering St. Paul's Cathedral financed by the city's merchants. The structure was built from the Baumberger sandstone found in the neighboring Baumberge mountains and is the northern end of the Prinzipalmarkt. St. Lamberti is the most important sacred building of Westphalian late Gothic. It is named after Saint Lambert of Liège.
A special feature of the church are three iron baskets hung on the tower. In 1536, the bodies of the three leaders of the Anabaptist kingdom of Münster (formerly known as Anabaptists) Jan van Leiden, Bernd Krechting and Bernd Knipperdolling were displayed after torture and execution.
Every evening (except Tuesdays) the watchman, one of the last in Europe, climbs the church tower and blows his horn every half hour from 9 p.m. to midnight. The watchman's office has existed since 1379, and it is his job to warn the townspeople of dangers (such as fires). A woman has held this position for the first time since 2014[1] (the other two active tower keepers are on duty in the Paul Gerhardt Church in Lübben and on the Blue Tower in Bad Wimpfen). In addition, the three will-o'-the-wisps, placed there by Lothar Baumgarten as part of the sculpture projects 1987, burn in the baskets in the evening hours as the appearance of three souls or inner fires that cannot find rest.
