Llantwit Major Monastic Settlement (Site of) is a medieval grange situated in Wales and protected by Cadw under reference GM142. The grange formed part of the monastic landholdings typical of medieval religious houses, which accumulated substantial agricultural estates to support their communities. Granges functioned as focal points for the management and exploitation of these outlying lands, often housing storage facilities, workshops and accommodation for lay workers and seasonal labourers engaged in farming operations.
The site lies upon bedrock of the Lias Group, comprising mudstone, siltstone, limestone and sandstone formed during the Aalenian period. This geology would have influenced both the character of the surrounding agricultural land and the building materials available for construction. Medieval granges of this type were economically significant enterprises, organised on a larger scale than individual peasant holdings and instrumental in the agrarian prosperity of monastic institutions during the medieval period.
The designation as a Site of reflects the archaeological status of the monument, where structural evidence survives beneath ground level or is no longer visible above the surface. Such sites remain important for understanding the spatial organisation, economy and daily operations of medieval monastic communities and their relationship with the wider Welsh landscape.
