[2][3] A scheduled monument is a nationally important archaeological site or monument which is given legal protection by being placed on a list (or "schedule") by the Secretary of State for Culture, Media and Sport; Historic England takes the leading role in identifying such sites.
They range from prehistoric standing stones and burial sites, through Roman remains and medieval structures such as castles and monasteries, to later structures such as industrial sites and buildings constructed for the World Wars or the Cold War.
Two major religious sites in Mendip at Glastonbury Abbey and Wells Cathedral and their precincts and dispersed residences, tithe barns and The Abbot's Fish House, are included in the list.
[18][19][20][21] Commercial and industrial development is represented by the Old Iron Works at Mells and various market crosses.
[22][23] The most recent site on the list is a World War II bombing decoy complex and anti-aircraft obstructions, which were built in 1940, on Black Down, the highest point of the Mendip Hills.
