The town of Llandeilo sits on a green and pleasant hill overlooking a bend in the River Towy (Afon Towy in Welsh) which is the longest river to flow entirely within  the borders of Wales.

A little history

  Llandeilo is proud of its 2000 year long history.  The recent discovery of two Roman forts confirms the existence of a village on this site since the first century AD.  Situated on the side of the hill above a river, it is not surprising that the Romans chose to site a fort in this easily defended place.

  Llandeilo is named after Saint Teilo, a contemporary of Saint David, who lived in the 6th century AD.  Saint Teilo is an example of the shared history of Brittany and Wales as traces of his passage through Brittany can be seen in the names of Breton villages and religious sites as well.  In Finistère his name is seen in the commune of Landeleau and the chapel of Saint Thélo at Plogonnec where there is a wooden, polychrom statue of him inside and a granite sculpture of him riding a stag on the outside (see Calendar - Visit 2010).  In the department of the Côtes d'Armor, a small coastal community bears the name Saint-Thélo.

  By the 9th Century, the ecclesiastical community founded by St Teilo at Llandeilo had become one of the most important and influential in Wales.  The neighbouring community of Dinefwr was of paramount importance in Welsh history as the seat of the powerful Welsh rulers of Deheubarth, the medieval principality of South-West Wales, whose forces fought against the Norman rulers of England until the power of the Welsh Princes was detroyed by Edward 1st at the end of the 13th century.

  In the 14th century Llandeilo itself developped into a prosperous town as Dinefwr declined and little remains of the latter except for the ruins of its magnificentt castle whose grounds are part of Llandeilo.  Llanedilo expanded during the 18th and 19th centuries with the construction of a new bridge over the River Towy and the arrival of the railway.


  Today Llandeilo, on the edge of the Brecon Beacons National Park, is a small but thriving market town in Carmarthenshire, with 2,900 residents in 2010.  The county town of Carmarthen with 14,600 residents is nearby and Cardiff, seat of the Welsh Parliament is only 60 miles away.   From whichever direction you approach Llandeilo, the town rises up to greet you as though posing for a photograph.  Behind the stone bridge and river, colourful houses line the street leading to the church and town centre.

The natural beauty of the surrounding countryside, a mixture of rolling hills and picturesque valleys, and the ever-present reminders of Llandeilo's heritage, give the area some exceptional sites to visit.  Amongst the many not to be missed are:
  • the Brecon Beacons National Park,
  • St Teilo church, whose square tower dates back to the 13th century.
  • the ruins and grounds of Dinefwr Castle (12th century), which was, in mediaeval times, the capital of South West Wales.
