The castle was erected at the beginning of the 13th century on the initiative of Llywelyn the Great, as a watchtower along the main route through North Wales. According to tradition, Dolwyddelan was the place of his birth, although it is now believed that he was born in Tomen Castell, a small tower that had previously stood on a nearby hill. Llywelyn was the greatest builder of castles among Welsh rulers, he tried to strengthen his power, building strongholds in Castell y Bere, Deganwy, Dolbadarn and Dolwyddelan. His death in 1240 weakened Wales and contributed to the struggles of his inheritance.
Until 1255 Llywelyn ap Gruffudd (Last) defeated his opponents, and under the Treaty of Montgomery was in 1267 recognized by the English and Welsh as the ruler of Wales. However, when Edward I became the king of England in 1272, relations with Llywelyn ap Gruffudd quickly deteriorated. This led to the First War of Independence, which took place in the years 1276-1277, in which Dolwyddelan, lying off the beaten track, did not take part. Llywelyn was defeated and forced to give control over all of Wales east of the Conwy River. The peace did not last long, however, because in 1282 the Second War of Welsh Independence was initiated by Dafydd ap Gruffudd, Llywelyn’s brother. Both were defeated, Llywelyn killed in the Battle of Orewin Bridge, and Dafydd escaped to Dolbadarn and eventually captured, he was executed by the English. In 1283 Dolwyddelan Castle was captured by Edward I during the final stage of the conquest of Wales. Staffed by the new garrison, it was repaired and expanded on the order of the king, to guard the peace of the newly conquered lands. However, as Edward I’s strategy focused on the fortresses that could be supplied by the sea, Dolwyddelan quickly lost its significance and the garrison was withdrawn until the 14th century. At the end of the fifteenth century, it was bought by Maredudd ab Leuan ap Robert, who made minor repairs. It is not known when the castle was finally abandoned, engravings from the eighteenth century show the castle already ruined. Dolwyddelan was restored in 1848-1850 by Baron Willoughby de Eresby.
The castle from the first half of the 13th century consisted of a tower – a keep on a rectangular plan, to which an irregular defensive wall was later added on the west side, adapted to the terrain of the hill. The tower had two floors with an entrance placed in the porch on the upper floor. The door was secured by a small drawbridge and ditch in the porch. On the second floor of the keep there was a main chamber, warmed by a fireplace, on the lower level there was a hatch in the floor and a ladder. The doors in the south – west corner of the first floor led to the corridor with a latrine at the end. The third storey was added to the tower in the second half of the 13th century or at the end of the 15th century, as a result of which it reached a height of 12 meters.
The second two-storey tower was added in the north-west corner by Edward I during renovations in the years 1283-1284. It also had a fireplace on the top floor, to which the internal stairs led. There was a latrine in the north corner.
A dry moat, partly carved in the rock, has protected the castle from the east and west. The entrance to the castle was provided by a simple wicket gate near the western tower, in the northern curtain. On the southern side of the keep, traces of the oven were discovered, but it is not known in what period it was made.
To date, the main eastern tower – keep – has survived, one of the most valuable examples of the native Welsh construction of this type, although the battlements are a nineteenth-century addition. Only the eastern wall has survived from the west tower, and the defensive wall can only be seen in the form of foundations. The castle is open to visitors.
