Folly of a Ruin
In England, the ‘landscape garden’ was very popular in the mid-to-late 18th century. This type of garden meticulously recreates landscape paintings of ancient Rome and other scenes of antiquity.
Landscape gardens feature decorative structures, called ‘follies’, in the shape of ruins and the like, in order to recreate the atmosphere of ancient landscapes.
The ruin-like folly in Nanatsudo Park was also used in the movie Thermae Romae, in the scene where the hero constructs a private bath.
