Brockenhaus, Visitor center and museum in Schierke, Germany

Brockenhaus is a visitor center and museum in Schierke that spans multiple levels, offering information about the natural environment and heritage of the Harz mountains. The spaces contain exhibits on geology, plant and animal life, and the development of this mountain region.

The present three-storey Brockenhaus was built from 1983 as a listening station for the Ministry for State Security of the GDR. Its prominent dome, erected for surveillance technology, earned it the nickname "Brocken Mosque" or "Stasi Mosque". After the summit reopened to the public on 3 December 1989, innkeeper Hans Steinhoff opened the Café Hexenklause in the building. The Brockenmuseum, founded in 1991 in an old radome, moved here on 1 June 1993; the house was rebuilt from August 1998 and the museum reopened in June 2000.

The museum's exhibition covers the Brocken's history, the national park's development and Brocken mysticism with its devils and witches. The building is nicknamed the "Brocken Mosque" or "Stasi Mosque" for its dome, and the Harz hiking pin stamp point No. 9 is located here.

The center provides orientation assistance, hiking maps, and information about the best routes in the surrounding area. Visitors should plan time to explore the different levels and learn about the local environment.

The building's dome, which earned it the nickname "Brocken Mosque" or "Stasi Mosque", still houses the historic antenna installations of the GDR Ministry for State Security, and visitors can tour them. The roof of the Brockenhaus is also open to walkers.
