First mentioned in a document dating from 1195 and finding more or less its present shape and form around 1320, the mammoth St. Petri is a classic Gothic design with three naves and high, arched ceilings. Almost completely destroyed during the Great Fire of 1842, St. Petri was rebuilt seven years later and is more or less as it was before the disaster. The inside is worth a look not least for what can only be described as a wholly awe-insipiring pulpit, as is a trip to the top of the steeple which affords by far the best view of the city. The church has a large modern organ, and free concerts are given every Wednesday at 17:00.
