In architecture, a folly is a building constructed primarily for decoration, but suggesting through its appearance some other purpose, or of such extravagant appearance that it transcends the range of garden ornaments usually associated with the class of buildings to which it belongs.
18th century English gardens and French landscape gardening often featured mock Roman temples, symbolizing classical virtues. Other 18th century garden follies represented Chinese temples, Egyptian pyramids, ruined abbeys, or Tatar tents, to represent different continents or historical eras.
