The Thick Tower (German: Dicker Turm, pronounced [dɪkɐ tʊrm]) erected in 1250 is part of the historic fortification of Görlitz.

However the fighting platform was walled up and a new copper hood in Renaissance style was added in the 16th century.

Originally the inner gate was connected to the city walls and stood in front of the tower on the Stone street.

The middle passage was covered with a building and had a portcullis made of wood and equipped with iron shoes.

The sandstone relief by Briccius Gauske on the tower depicts this coat of arms together with the two figures of Mary and Saint Barbara.
