The Old Town Hall was once the seat of the Old Town council. A well-proportioned Renaissance building crowned with a high central tower typical of its Flemish provenance, it was designed at the end of the 16th century by Antonius van Opbergen, the architect later responsible for the Great Arsenal. The brick structure is delicately ornamented in stone, including the central doorway and a frieze with the shields of Poland, Prussia and Gdańsk.

The building now houses the Baltic Sea Culture Centre and an exhibition hall. Go upstairs to see the foyer, notable for its rich decoration, which was partly assembled from old burghers’ houses. Note the arcaded stone wall (1560) with three Roman gods in bas-relief. This composition, older than the town hall itself, was moved here from one of the houses in the Main Town. One of the doors leads to the Great Hall, which can also be visited. Concerts are held here; check the program for details.
