Llantwit Major

The college suffered during the invasions of the Saxons and the Danes and was destroyed by the Vikings in 987 and again by the Normans in the late 11th century. However, in 1111, it is documented as being restored, but likely in a lesser state than the original. It is known to have continued to function as a monastic school until the 16th-century Reformation. The ruins of the original school house are located in a garden on the northern end of the churchyard and the monastic halls were located in a place called Hill-head on the north side of the tithe-barn. Although nothing of the original monastery remains, the present church was originally built between 950 and 1400 and its earliest existing secular buildings date from the 15th century. The church and school became the property of Tewkesbury Abbey around 1130 after becoming part of the Norman kingdom of Glamorgan.
