LGBT權利運動
From December 2004 to May 2013, there was a permanent exhibition called "Selbstbewusstsein und Beharrlichkeit. 200 Jahre schwule Geschichte" ("Self-Awareness and Endurance: 200 Years of Gay History"). It covers period 1790 to 1990, showing how gay people met up with each other and organised networks, and depicted the strategies, options and problems of gay people in seeking to live a self-determined life. In association with this theme, the social and legal background was presented, such as the anti-gay Paragraph 175 of the German penal code; the associated marginalisation, persecution and criminalisation of homosexuality; as well as the successes of LGBT social movements.
