Brief History
The castle was built between 1210 and 1240 by Llywelyn ap Iorwerth, known as Llywelyn the Great. He was one of the most powerful Welsh rulers and sought to strengthen his control over Gwynedd. The castle acted as a defensive fortification and a symbol of authority in the Lledr Valley.
In 1283, it fell to Edward I of England during his final conquest of Wales. The English forces made minor modifications, including the addition of a second storey to the keep and a new entrance with a drawbridge. Despite these changes, the castle lost strategic importance soon after Edward’s conquest.
By the 15th century, the castle had fallen into disrepair. It remained largely abandoned until restoration work began in the 19th century. Lord Willoughby de Eresby oversaw repairs in the 1840s, rebuilding parts of the keep for preservation purposes rather than active use.
Today, the castle stands as a ruin but retains much of its original character. It provides insight into native Welsh castle design, distinct from the Norman or Edwardian styles seen elsewhere in Wales.
Features and Layout
The castle consists mainly of a rectangular keep with thick stone walls. The keep stands on a natural rocky mound, providing a strong defensive position. The interior includes a vaulted basement and a first-floor hall. English additions created a second floor, but only the lower floors remain accessible today.
A surrounding curtain wall enclosed the castle courtyard, though much of it has been lost. Foundations of a second tower, known as the West Tower, are still visible but in ruins.
The castle’s design follows traditional Welsh military architecture. It prioritised functionality over decoration. Narrow slit windows provided light and defence. The entrance was originally accessed by a wooden staircase, now replaced with modern steps for visitors.
Did You Know?
Carved graffiti dating from the 19th century can still be seen on some interior walls, left by early tourists and workers during restoration.

Legends and Stories
The castle holds few surviving myths, but local tradition claims it was the birthplace of Llywelyn the Great. This story appears in guidebooks such as the Cadw visitor panels at the site. However, historians have debated its accuracy, suggesting he was more likely born in nearby Tomen Castell, a smaller fortification visible from the castle.
Another tale describes it as a symbol of resistance during the final years of Welsh independence. Local oral history, as mentioned in Visit Conwy's tourism guides, recounts how the castle stood firm until Edward I's armies overcame it in 1283.
Visitors on TripAdvisor frequently mention the atmospheric setting, with some noting feelings of isolation and the echoes of past Welsh defiance while standing in the ruins.
