Klinkerwerk, Former brick factory in Bergedorf, Germany

Klinkerwerk is a former brick factory in Bergedorf consisting of multiple buildings, a tall chimney, and production halls built near the Elbe River for manufacturing clinker bricks. The site comprises various structures that have been preserved and repurposed in different ways.

On 3 September 1938 the SS bought the Neuengamme site through Deutsche Erd- und Steinwerke; a month later 100 prisoners arrived from Sachsenhausen and Neuengamme became a subcamp. The bricks were meant for clinker facades in Hamburg's planned redesign as a Führer city. A 13 April 1940 contract obliged Hamburg to finance the camp in exchange for bricks for its new buildings. The western half of the new works opened on 15 July 1942.

The eastern wing houses the exhibition "Arbeit und Vernichtung: KZ-Zwangsarbeit in der Ziegelproduktion", on forced labour in brick production. From it visitors can see part of the surviving drying ovens; the former sump basins are largely in their original state apart from alterations made by a Swedish concrete firm after the war.

The eastern wing holds the exhibition "Arbeit und Vernichtung: KZ-Zwangsarbeit in der Ziegelproduktion"; the western wing is empty and used only for occasional large events. The central section is closed to the public because of poor structural condition, and its cellar stands under water pressing up through the floor. The former Spar apartment can be entered only from the rear, is at risk of collapse and has large holes in the floor; surviving drying ovens and the former sump basins can be viewed from the exhibition.

The site's former settling basins survive almost intact, apart from alterations made by a Swedish concrete firm that bought the buildings after the war. The cellar of the middle section stands under water, which now presses up through the floor.
