The Stadhuis on the Markt is a confident piece of 17th-century Dutch classicism, designed by Pieter Post and completed in 1664. The double staircase at the main entrance is the defining feature — it was designed so that the city's Spanish and Dutch governors, who shared power over Maastricht under the peculiar arrangement that lasted until 1794, could each enter without yielding precedence to the other.
The building is still the working seat of the municipal government and can be visited. The ceremonial rooms on the upper floor retain their original furnishings and painted ceilings. The Markt around it hosts a good general market on Wednesday and Friday mornings — one of the better food markets in the south of the Netherlands.
