Merlin's Hill has, at its summit, the site of an Iron Age Hillfort. Dating back to around 400 B.C., it is one of the few large hillforts in West Wales whose size alone suggests that they were centres of power controlling large territories.
When the Roman armies entered the Towy Valley in AD 75 and established first a fort and then a town at Moridunum, the modern Carmarthen, the hillfort may still have been a focus of economic power, perhaps for tribal gatherings.
In 1188, Gerald of Wales wrote that Merlin was born in Carmarthen. Merlin - King Arthur's guardian with magical powers - is believed to have lived in a cave on Merlin's Hill. This cave was to serve as his home and tomb as, according to legend, he was locked there in bonds of enchantment by his lover. Alas, the cave has become lost with the passage of time but many still hear Merlin clanking his chains on Merlin's Hill.
Please Note: The footpath leading from across the farmyard to the hilltop is private and has been created by the owners of Alltyfyrddin Farm and the Merlin's Hill Centre for the enjoyment of their guests.

We regret that due to the nature of the terrain, the hill avails very little access to the disabled, however, the farmyard and heritage centre are wheelchair friendly.

Alltyfyrddin is also home to the Myrddin flock of Jacob sheep, one of the largest flocks of pedigree Jacob sheep in the UK. This is an ancient breed and is mentioned in the Bible, they have two or four horns and have spotted fleeces. Admire and buy items from the Merlin's Hill Wool Collection - this is made from 100% pure wool from our flock of Jacob sheep which is naturally reared on Merlin's Hill. The breed's unusual colourings has provided the inspiration to create this exquisite collection of fabrics from their undyed wool. The collection includes scarves, throws, knee rugs and cushions, and are wonderful reminders of your visit to Carmarthenshire.
