Caerleon Castle | Visit Amazing Welsh Castles
Caerleon Castle was a likely medieval fortification in Caerleon, Newport, South Wales.
Believed to have been established by the Normans, or possibly a Welsh lord such as Caradog ap Gruffydd, to control key crossing points on the River Usk, the site may have played a role during the early phases of the Norman presence in Wales.
Today, only limited earthwork remains can be seen within the historic town, and the exact nature and extent of the medieval fortification remain uncertain.

Brief History
Caerleon is best known for its extensive Roman fortress, Isca Augusta, but there is some evidence to suggest the Normans, or possibly a Welsh lord like Caradog ap Gruffydd, may have established a fortification here in the late 11th century. It is possible that a temporary motte-and-bailey-style stronghold was constructed around 1085 to consolidate control in South Wales. However, no definitive archaeological evidence of a Norman castle survives, and the identity of the builder remains uncertain.
During the medieval period, Caerleon remained strategically significant and changed hands between Welsh and Norman powers. While some historians have speculated about the reuse of earlier Roman defences for medieval purposes, there is currently no archaeological evidence confirming such reuse. By the 13th century, any such fortification had likely fallen into disuse.
Features and Layout (Speculative)
If a Norman castle did exist at Caerleon, it was likely a typical motte-and-bailey structure. The motte, an artificial mound, would have supported a timber keep for defense and oversight. Attached to it would have been a bailey, a courtyard enclosed by palisades and ditches, housing living quarters, storage, and stables.
Today, no castle structures survive. However, visitors can see earthworks in the area—especially near the Roman amphitheatre and fortress—which may relate to medieval re-use or defensive modifications. These features, combined with the site's layered history, offer a compelling glimpse into Caerleon’s complex past.
Did You Know?
During archaeological investigations at the site, Roman remains were discovered beneath the medieval-era layers. Caerleon was originally a Roman fortress named Isca Augusta, established almost a millennium before the Norman structure may have appeared.

Legends and Stories
Local legend connects Caerleon to the legendary court of King Arthur. In the 12th century, chronicler Geoffrey of Monmouth famously described Caerleon as one of Arthur’s primary seats of power in his Historia Regum Britanniae. According to Geoffrey, Arthur held magnificent feasts and gatherings here, surrounded by knights, clerics, and nobles from across the realm.
While there is no archaeological evidence linking the castle or the Roman fortress directly to the historical Arthur, or confirming Camelot’s existence, the association has endured through centuries of Arthurian romance and literature. Today, this enduring myth continues to attract visitors curious about Caerleon’s legendary past.

Wrapping it Up
This castle offers a glimpse into Norman military architecture through its surviving earthworks, though no standing structures remain, and much about the original fortification is still debated. Its historical importance lies in controlling strategic routes in South Wales during the early medieval period. While the exact builder remains unknown, the castle may have been established by Norman forces or a local Welsh lord around the late 11th century.
Today, the site’s interest lies in its layered history, where possible medieval features sit near the much older Roman fortress of Isca Augusta. Visitors often combine a walk to the earthworks with a tour of Caerleon’s Roman baths, amphitheatre, and museum, gaining a broader appreciation of the area's rich archaeological and cultural heritage.
