What is follies definition?

Follies are architectural constructions that are often elaborate and built for ornamental purposes. They can be found in gardens, parks, and other outdoor spaces. Follies are typically designed to look like ruins, classical temples, or fanciful structures that serve no practical purpose. They are often built as a statement piece or to enhance the aesthetic of the surrounding environment. Follies can be made out of a variety of materials, including stone, wood, and metal. Some are small and simple, while others are large and intricately designed. Follies have been popular in Europe since the 16th century and continue to be a common feature in many landscaped gardens and parks around the world.
