Another one: The "Bergpark Wilhelmshöhe" in Kassel, Germany.

This is a masterpiece of Baroque landscape architecture, and the Hessian landgrave at the time was only able to afford it because his father sold of Hessian subjects to the British so that they could put a stop to those pesky rebels in the North American colonies. The park is built across a hill slope (and covers an elevation change of more than 250 meters). Its highlights are the "Wasserspiele" ("Water Plays"). On every Sunday and Wednesday during the warmer seasons, water is released from a vast cistern at the top, located beneath a giant bronze statue of Hercules. Over the course of 75 minutes, this water flows down a series of artificial waterfalls and channels until it powers a giant fountain close to the bottom of the park.

Beyond that, the park has all sorts of other attractions - a fake ruined castle, a fake ruined Roman aqueduct, and a series of miniature temples to assorted Roman gods. This park makes a perfect setting for all sorts of cinematic adventures and/or occult weirdness!
