Berlin sagt Danke: free museum entry for volunteers.

"Berlin sagt Danke" is a day of action on which Berlin thanks everyone who does volunteer work. Holders of the Ehrenamtskarte (volunteer card) get free entry that day to three museums in the Nikolaiviertel, the oldest part of Berlin. The Ephraim-Palais covers Berlin stories, the Knoblauchhaus the Biedermeier era, and the Nikolaikirche the city's beginnings. The museums belong to berlin.museum, and the image credit names the Senatsverwaltung für Kultur und Gesellschaftlichen Zusammenhalt in connection with the day.
