Ernst-Thälmann-Park is a park in the centre of the Prenzlauer Berg district in Berlin. It was laid out in 1986 at the site of a former coal gas plant and named after the former Communist party leader Ernst Thälmann.
The former plant built in 1874 was closed in 1981, the last gasometer was demolished in 1984. In honor of Berlin's 750-year jubilee the East German government drew up plans for an "inhabited park", including a memorial, a public pool, a planetarium, a school and a housing estate for 4,000 residents. The park was inaugurated on 16 April 1986, Thälmann's hundredth birthday.
