26th Heritage Open Day in Berlin

Around 100 years ago, Berlin was the European centre of the electrical industry and cradle of the second industrial revolution. The 26th Denkmaltag or Heritage Open Day on 17 April 2012 celebrates this chapter in the city's history and examines its potential to gain world heritage status. You can also see the 'Elektropolis Berlin' photography exhibition at the Modellsaal in Köllnischer Park until 3 May 2012.
