On the site of the early Gothic predecessor building on Rottenburg’s market square, a vaulted, three-nave basilica was built in the mid-15th century. On closer inspection, one discovers how unusually St. Martin’s Cathedral is built. The ground plan is very irregular due to the course of the street. The Romanesque base of the 58-meter-high tower, which is now a landmark of the city, protrudes into the chancel of the church. After the city fire of 1644, St. Martin’s Cathedral was restored in the Baroque style. Due to this unconventional style of construction, there was also initially resistance in the Catholic Church to the decision to declare the cathedral the seat of the bishop.
