A Royal Seat of Medieval Welsh Power

Llys Rhosyr stands as a unique archaeological site near Newborough on the island of Anglesey, representing the only surviving medieval court of the Welsh Princes that visitors can explore today. Established in the early 13th century, it functioned as a royal residence and administrative centre for the Princes of Gwynedd, notably Llywelyn the Great, who ruled much of Wales for four decades. The site was a hub for governance, where princes held court, dispensed justice, collected taxes, and hosted official events.

Excavation and Rediscovery

After falling into disuse following Edward I's conquest of Wales in 1283, Llys Rhosyr was buried by a fierce sandstorm in the early 14th century, obscuring it for centuries. Archaeological excavations led by the Gwynedd Archaeological Trust between 1992 and 1996 uncovered the site's layout, revealing a well-preserved perimeter wall and foundations of several large buildings, including a great hall with an off-centre hearth, chambers, and storage barns. These remains provide rare insight into the secular architecture and lifestyle of Welsh medieval royalty.

Architectural and Cultural Significance

The layout and scale of Llys Rhosyr illustrate the sophistication of princely courts in medieval Wales. The hall discovered rivals the size of the largest known halls in Gwynedd, indicating the site's importance. Despite the grandeur, archaeological evidence suggests the princes lived a relatively modest lifestyle. The site’s open courtyard and ancillary buildings reflect its role as a multifunctional centre of power, administration, and daily life.

Modern Preservation and Interpretation

Recognised for its cultural and historical importance, Llys Rhosyr was designated as Cadw’s 131st scheduled monument, ensuring its protection and conservation. To bring the medieval court experience to life, two of Llys Rhosyr’s buildings were reconstructed as Llys Llywelyn at St Fagans National Museum of History, showcasing experimental archaeology and allowing visitors to engage with Welsh royal heritage. The original site offers scenic views across the Menai Strait to the mountains of Snowdonia, enhancing its sense of place and historical context.

Visitor Experience and Surroundings

Today, visitors can explore the exposed foundations and walls, imagining the royal activities that once took place here. The site is accessible via a short walk from Newborough and is free to visit. The surrounding landscape, including views toward Eryri (Snowdonia), enriches the visit, connecting the ruins to the natural environment that shaped medieval Welsh life. Events such as medieval feasts and music gigs are occasionally held at the related reconstructed buildings, deepening public engagement with this heritage.

Legacy of Welsh Princes Preserved

Llys Rhosyr embodies the legacy of the Princes of Gwynedd and their governance before English conquest. Its archaeological and historical significance offers a tangible link to Wales’ medieval past, revealing the complexity of princely courts and their role in Welsh identity. As a protected monument, it continues to inspire interest in Welsh history and culture, preserving the story of native rule amid centuries of change.
