The organ music at market time in Überlingen's St. Nicholas Minster takes place in May, June, July, September and October on the first Saturday of each month. At 11:30 a.m., organ music is played for about 30 minutes as a musical counterpart to the hustle and bustle of the market. There is time and space in the minster to take a break from the stress of the week with this music and to get to know the tonal possibilities of the St. Nicholas organ. Well-trained organists and church musicians from the near and far region contribute to the success of this concert series. Admission is free.
