The Prague Gate belonged to the original town fortification. Construction probably began in the late 13th century (the fortification was mentioned in Přemysl Otakar II.´s document from the year 1274 ). The town‘s fortification was reconstructed during the Hussite wars and remains of it have been preserved since that time. The town was accessible through two gates; the Prague and the Elbe. The Elbe gate and most parts of fortification were destroyed in the 19th century.
An interior reconstruction of the upper two floors took place in 1997 thus creating a room suitable for the gallery´s activities. On the fifth floor there is a glassed-in room with a beautiful panoramic view of the surrounding landscape.

Today´s floor plan is different from the original of 1536. It was changed after the interior was destroyed by a fire in 1652 and repair work followed after another fire that occurred in 1799. The gate was again renovated by architect Kamil Hilbert from 1916 to 1920.
