Llantwit Major is a coastal town located in the Vale of Glamorgan, South Wales. The city of Cardiff is just 15 miles away, whilst Swansea can be found 30 miles to the north west.

Llantwit Major sits on the Glamorgan Heritage Coast between Tresilian Bay and Stout Bay, and the Valeways Millennium Heritage Trail wends its way through the town from St Donats in the west en-route to Boverton and Llanmaes. The beach at Llantwit Major beach is mostly pebbles and rock, with a few stretches of sand. Several fossils have been found and there are a number of caves to explore. It is a popular place with anglers, surfers and swimmers, but beginners to surfing should take care as the waters can be dangerous depending on weather conditions.

St Illtuds Church is the parish church of Llantwit Major. Christianity is believed to have been practised at Llantwit Major since Roman times. The church is a quirky building made up of two churches, the monastic church and the parish church. A tower was added to the east side during the 13th century, and in 1400 both the east and west sides of the church were extended, and the roof and tower raised. During the 14th century the upper walls of the south porch were extended. A dovecote still stands a few yards away from the main building and the church acts as an impressive building in Llantwit Major today.

The town is famous for being home to the “oldest university in the world.” Early in the 6th century St Illtyd set up his "Llan" at Llantwit Major and founded a monastery-university, after pirates destroyed the first church here. The university was to make its mark on Wales, with pupils such as Taliesin, Saint Gildas, Saint Baglan, King Maelgwn Gwynedd, Saint Tudwal, Saint Samson and even Saint David. Little remains of the university today but its ruins are still a sight worth seeing.

There are regular train services to Bridgend, Cardiff Central and Merthyr Tydfil from Llantwit Major railway station.
