It is possible that each enclosure within the site was representative of different groups, and pictographs within the walls aligned with clans beliefs or traditions. The Three Age System and common archaeological enclosure sites The Stone Age (3.4 mya - 2000bce) Causewayed Enclosures One example of an enclosure suggested to be created in the Neolithic Stone Age are causewayed enclosures (otherwise referred to as ‘causewayed camps’). They are the earliest known form of open space enclosures. It is believed causewayed enclosures originated in mainland Europe and spread through France, Germany, Scandinavia and the British Isles. The enclosures are characterised by their oval or circular shape, and often having a concentric circuit for banks and ditches of up to 20 meters long. It is suggested the functions of the enclosures were for communal meetings, settlement, and burial sites. The Bronze Age (3300 - 1200 bce) Cursus Monuments Cursus monuments are archaeological enclosures most commonly noted throughout British, Scottish and Irish earthwork. They are characterised as being long, narrow pairs of enclosures generally dating back to 4000-2500BC. Cursus monuments often resemble ditches in the ground, as their rectangular walls are often outlined structurally by materials such as wood. These monuments are most often discovered through aerial imaging, and other ground penetrating methods. These enclosures range in length from 10km (as seen in the Dorset Cursus), to around 50 meters approximately. There is no approximate width of any known cursus monuments, as it varies depending on the purpose. There are few entrances to cursuses enclosures, but most often seen as gaps along the side of the earthwork. The purpose of cursus monuments are considered mostly to be used for guides, barriers for districts, and most commonly for ritualistic and ceremonial purposes. Mar Hall The Mar Hall enclosure is a small, horse-shoe shaped enclosure appearing in southern Scotland, and was excavated in 2007. Mar Hall was an enclosure site predicted to have been formed within the Bronze Age. It appears certain that activity took place within the inner-ring grooves of the enclosure, and was likely not used for domestic practises due to its lack of diagnostic material. The Iron Age (1200 - 550 bce) Banjo Enclosures Banjo enclosures are a prominent enclosure type found commonly in the British Middle Iron Age. They are characterised by their small, sub-circular outline, and single entrance, and usually connect to a wider field or paddock. The rounded enclosure
