The headquarters of the Gdansk History Museum are housed in the Town Hall, which  is a Gothic-Renaissance building, located at the corner of Dluga Street and Dlugi Targ, dominating the panorama of the Royal Route – the most representative route of the listed part of the city. The origins of the Town Hall, which from the very beginning was the seat of the authorities of the main Gdansk area, from the 14th century referred to as the Main City, go back to the early Middle Ages. From the mid 15th century it became the centre of power for the entire area located on the Motława river. It served this function for a few centuries, and throughout this time was the main municipal building.

The first floor features the most important rooms of the Town Hall – the Great Council Hall, also called the Red Hall, and the Great Wety Hall, from the 19th century called the White Hall. Beautiful rooms were also created inside the annex, to which two wings (northern and eastern) were added in the 16th century, which include the Small Council Hall (also called the Winter Hall) and the Small Wety Court Hall (the Fireplace Hall). The annex and the side wings formed a rectangular internal courtyard.

At present, exhibitions presenting Gdansk history are held at the Town Hall. The splendid building also performs reception functions. During the tourist season (in the spring and summer), the sightseeing gallery of the tower is open to tourists, and at around 50m high the tower provides a great view of Gdansk.
