The Llantwit Major Roman Villa was a Roman L-shaped courtyard villa located at what is now Caermead, immediately north of the town of Llantwit Major in the Welsh county of South Glamorgan.

The site developed slowly and, it has been suggested, was even abandoned for a while during the 3rd century.

By the 4th century, there was an L-shaped villa with fine mosaic floors, a large aisled building possibly for farm workers and a number of smaller agricultural structures almost enclosing a central courtyard.

[1] Part of the site was used as a cemetery in the early medieval period.

[1] The excavations of 1971 uncovered two burials which had been dug through the tesselated pavement of rooms 8/9.
