An eventful history: Greifswald Town Hall was built in 1250 when the town received its town charter. In 1713 it burned down to its foundation, and in the mid-1990s penetrating moisture endangered the historic ribbed vaults.

Protection of the basement from penetrating moisture was of major importance, as the town hall was, among other things, to be used as a guest house and showroom and for the artisan market in the Advent season.
