The Radolfzell Minster or Minster of Our Lady in Radolfzell on Lake Constance is a three-nave, eight-bay pillar basilica from the late Gothic period. The construction of the Radolfzell Minster began in 1436; There are no remains of the presumably Romanesque predecessor building and the layout of Bishop Radolt of Verona († 847). In 1488 the construction was temporarily completed and the choir was consecrated.
