Folly
In architecture, a folly is a building constructed primarily for decoration, but suggesting through its appearance some other purpose, or appearing to be so extravagant 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 Roman temples, which symbolized classical virtues or ideals. Other 18th century garden follies represented Chinese temples, Egyptian pyramids, ruined abbeys, or Tatar tents, to represent different continents or historical eras. Sometimes they represented rustic villages, mills and cottages, to symbolize rural virtues. Many follies, particularly during famine, such as the Irish potato famine, were built as a form of poor relief, to provide employment for peasants and unemployed artisans.
In English, the term began as "a popular name for any costly structure considered to have shown folly in the builder", the OED's definition, and were often named after the individual who commissioned or designed the project. The connotations of silliness or madness in this definition is in accord with the general meaning of the French word "folie"; however, another older meaning of this word is "delight" or "favourite abode" This sense included conventional, practical, buildings that were thought unduly large or expensive, such as Beckford's Folly, an extremely expensive early Gothic Revival country house that collapsed under the weight of its tower in 1825, 12 years after completion. As a general term, "folly" is usually applied to a small building that appears to have no practical purpose, or the purpose of which appears less important than its striking and unusual design, but the term is ultimately subjective, so a precise definition is not possible.
