The construction start of the St. Marien Church, which is also called the "fat Marie" by the citizens of Greifswald, probably dates back to the middle of the 13th century. Together with the two other city churches of St. Nikolai and St. Jacobi, it is first mentioned in a document in 1280. The church was built as a hall church and is one of the most impressive testimonies of North German brick Gothic today. Worth seeing inside the church are in addition to the preserved colored paintings (14th century), the medieval court hall, the large Lasten-Tretrad in the tower, the memorial chapel, the altarpiece - a replica of Correggio's "Holy Night" and the ornate pulpit (16 Century).
