Berlin's Spreepark had a promising start but eventually went bankrupt in 2001. It opened in 1969 and closed 20 years later when the Berlin Wall fell. The once thriving visitor numbers tanked and was purchased by a private investor in 1991 who tried to revive the park. Some of the popular rides were shipped out to be repaired but when they returned to Germany, customs officers found 167 kg of cocaine in the Flying Carpet. Plans were quickly shut down and its new owner served four years in jail. The park has remained fenced off but might reopen in the near future for guided tours.
