I have arrived at the entrance of Spreepark, an abandoned amusement park tucked between the Plänterwald forest and Spree river on the outer reaches of Berlin, Germany. The site, located next to a sleepy suburban neighborhood dotted with weeping willows, stands in contrast to the bright, cosmopolitan downtown nearby.

The 60-acre site first opened in 1969 as the only amusement park in Soviet-controlled East Germany. It shut down in 2001 amid plunging attendance and was fenced off a year later. Spreepark fell into severe disrepair over the next decade, left open to the elements and to thrill-seeking trespassers. The rusted rides, overgrown weeds and dead quiet now give the place the feel of a sprawling, open-air Halloween haunted house mixed with an elaborate, interactive art installation.
