A Listed Building is a structure that has been officially recognized for its historical, architectural, or cultural significance. In many countries, including the United Kingdom, these buildings are protected by law to preserve their character and heritage. They can range from ancient monuments to modern constructions, and their listing helps ensure that any alterations or renovations are carefully managed. There are different grades of listing, such as Grade I, Grade II*, and Grade II in the UK, indicating the level of importance. Owners of listed buildings must seek permission for changes, ensuring that the unique features and historical value are maintained for future generations.
