Conwy Castle is one of the most complete and impressive medieval fortresses in Wales. Built between 1283 and 1287 by order of King Edward I, it played a crucial role in the English king’s campaign to conquer and control North Wales.

The castle forms part of Edward’s wider “iron ring” of defences, a network of strategically placed strongholds across Gwynedd.

Positioned above the River Conwy, the castle and its walled town were designed both to defend and to dominate. The massive curtain walls, eight towers, and well-preserved interior give visitors a rare glimpse into late 13th-century military architecture. It remains a symbol of Edwardian power and ambition in Wales.

Bodelwyddan Castle

Bodelwyddan Castle is a historic country house in Denbighshire, North Wales. Although it resembles a fortified structure, it was never built for defence.

Dolwyddelan Castle

Dolwyddelan Castle stands on a rocky outcrop in the Lledr Valley, Conwy County, North Wales. It is a single-tower keep built during the early 13th century.

A Brief History

The castle was built between 1283 and 1287 during King Edward I’s invasion of North Wales. It formed part of his larger campaign to control the region and was constructed alongside the fortified town of Conwy. Both were designed to assert dominance over the Welsh population.

The castle's architect, James of St George, was a Savoyard mason brought in by Edward. He used a design that made best use of the rocky coastal outcrop. With its high curtain walls and eight towers, the structure provided both strong defence and clear lines of sight across land and sea.

In 1294, during a Welsh uprising led by Madog ap Llywelyn, it was besieged. Edward himself was trapped inside for several months over the winter, supplied only by sea. The castle held firm, proving its strength.

During the 14th and 15th centuries, the castle saw periods of neglect and repair. It changed hands again in 1401 during the revolt of Owain Glyndŵr, when it was captured in a surprise raid.

By the 16th century, the castle had little military use and fell into disrepair. It was garrisoned briefly during the English Civil War but was slighted (partially dismantled) in 1665 to prevent future military use.

Today, although ruined, much of the structure remains intact, including interior rooms, spiral staircases, and the full circuit of the town walls.

Features and Layout

The castle has a compact, rectangular layout, shaped by the rocky ridge it stands on. It is divided into an outer ward and an inner ward, each defended by its own set of towers and walls.

There are eight massive towers in total. Four belong to the inner ward and four to the outer ward. All are circular and provide views across the town, river, and estuary. You can still climb several of them today.

The outer ward contained the barracks, storerooms, and other service buildings. A barbican protects the main gate on the town side. A second barbican faces the river, which allowed access to supplies by boat during a siege.

The inner ward is smaller but more secure. It housed the royal apartments, great hall, and chapel. The hall has lost its roof but remains clearly defined. Arched doorways and window openings still stand.

High curtain walls surround the castle and link all eight towers. The walls once supported wooden fighting platforms. You can still walk sections of the walls today, including the town walls, which stretch for over 1.2 kilometres.

There is no central keep, as the wall towers and inner ward provided sufficient defense and status.

Legends and Stories

The castle has its share of local tales, though many are based in folklore rather than fact.

One of the most repeated legends involves the chapel. Some visitors and guides speak of ghostly monks still seen in the quiet corners of the castle, particularly near the former royal chapel. Cold spots and odd noises have been reported, especially in the early morning.

Another story comes from the 1401 capture of the castle by two of Owain Glyndŵr’s supporters. Rhys and Hywel ap Tudur reportedly climbed the walls disguised as carpenters. Once inside, they seized control from the small English garrison. The story is notable not for myth, but for the fact that the daring raid succeeded without major bloodshed, a rare event in the revolt.

There are also tales of a hidden treasure buried within the castle by fleeing soldiers during the Civil War. No treasure has ever been found.

Although none of these stories are confirmed by written records, they add to the sense of mystery around the ruins.
