A historic site or heritage site is an official location where pieces of political, military, cultural, or social history have been preserved due to their cultural heritage value. Historic sites are usually protected by law, and many have been recognized with official historic status. A historic site may be any building, landscape, site or structure that is of local, regional, national, or global significance. Usually this also means the site must be at least 50 years or older.
Historic sites and heritage sites are often maintained for members of the public to be able to visit, with some offering tours or running visitors' centers.
