Aberystwyth Castle is a striking example of a coastal fortress built during the medieval period in Wales. You can find it in the town of Aberystwyth, Ceredigion.

The castle overlooks Cardigan Bay and offers views of the surrounding area. Today, the remains stand as an open ruin, providing insight into the military history of the region.

The castle was originally built in the late 13th century under the orders of King Edward I of England. It served both defensive and administrative purposes during the period of English expansion into Wales. Although only parts of the curtain walls and towers remain, it is recognised as a key landmark in Welsh history.

Brief History

Construction began in 1277. King Edward I ordered its building during his military campaigns to control Wales. The castle replaced an earlier motte-and-bailey structure known as Castell Tan-y-Castell, built by the Normans in the 12th century.

Work on the new stone castle finished around 1289. Its purpose was to secure English rule and suppress local Welsh resistance. The town of Aberystwyth grew around the castle, forming a planned settlement for English colonists.

During the 14th century, the castle experienced damage from Welsh uprisings, including the revolt of Madog ap Llywelyn in 1294–1295. Repairs followed each conflict, maintaining the site as a defensive stronghold.

In the early 15th century, Owain Glyndŵr captured the castle during his rebellion against English rule. The English crown later regained control. By the 17th century, the castle served less as a military base and more as a prison.

It saw final destruction in 1649 under orders from Parliament during the English Civil War. Parliamentarian forces slighted the structure to prevent its further use in conflict.

Today, the castle remains stand as a scheduled monument, reflecting centuries of political and military change in Wales.

Features and Layout

The castle was built following a concentric design. This means it had multiple lines of defence, with an inner ward surrounded by an outer curtain wall. Although much of the structure is ruined, several key features are still visible.

You can see the remains of the gatehouse, which once controlled access to the castle. The twin-towered gatehouse was the main entrance, designed for defence. Close by, fragments of the inner ward walls and towers show the original layout.

The castle also had corner towers. The most recognisable today is the north tower, where large sections of masonry survive. You can explore these towers and see arrow slits used by medieval archers.

A small chapel once stood within the inner ward. Only the foundations remain now, but the site helps to show the importance of religion within castle life.

Modern features include a memorial to those who fought in the First World War, placed within the castle grounds in the 1920s.

A unique feature is its coastal location. The defensive walls face the sea on one side, showing how the design protected from both land and maritime threats.


Did You Know?
You can still see carved medieval graffiti inside some sections of the walls. These markings show the castle’s long use by different groups, including prisoners in later centuries.

Legends and Stories

It features in several local legends and historical accounts. One tale describes a hidden treasure buried beneath the castle by Owain Glyndŵr during his early 15th-century rebellion. Though many have speculated, no such treasure has been found. This story is often mentioned in local tours and guidebooks, such as those offered by Visit Aberystwyth guides.

Another account comes from the English Civil War. Some sources, including historical plaques on-site, note that after the castle was slighted in 1649, stones from the ruins were used by townspeople to build local houses. This repurposing of castle material remains visible in older buildings around Aberystwyth.
