The construction of the castle began around 1240 Welsh lord Meredith ap Rhys Gryg. The stronghold was originally a timber and earth building, but soon it was rebuilt into a stone one, as one of the few that were built by the Welsh. The purpose of building the castle was rather the desire to have an administrative, not a defensive center, as Meredith’s main residence was in Dryslwyn Castle.
Emlyn became the property of Meredith’s son, Rhys ap Maredudd, who avoided involving in the First Welsh War of Independence, thanks to which he was awarded by king Edward I. Apparently the award did not meet Rhys’ expectations because he rebelled in 1287 and lost Newcastle Emlyn to Roger Mortimer, Earl of March. Rhys’s army recaptured the castle, but at the beginning of 1288 it was besieged and captured by Robert Tiptoft. Rhys ap Maredudd escaped and was later captured and executed in 1291. His estate, including Emlyn, was confiscated by the Crown.
In the fourteenth century, three successive kings of England: Edward I, Edward II and Edward III made the expansion and modernization of the castle. In 1312 a new great hall was put into use and it was probably at that time that the construction of a new twin-tower gatehouse was started. In the mid-fourteenth century, the castle and the town were significantly depopulated when the area was ravaged by the Black Death. Report from 1343 informed that the castle was in bad condition. Nevertheless, in 1347 it was repaired by Richard de la Bere on behalf of the Black Prince Edward. In 1382, it was awarded to Simon Burley.
In 1400, the Welsh rebellion of Owain Glyndŵr broke out, and he was proclaimed the Prince of Wales. The uprising quickly spread to southern Wales and in 1403 the Welsh forces came to Newcastle Emlyn. The castle was conquered and the town, whose inhabitants were largely of English origin, was plundered. However, soon, because in two weeks, this area was recaptured by Sir Thomas Carew. The damages must have been significant, since the report from 1428 described the castle as ruined.
At the end of the 15th century, the Tudor dynasty of Welsh origin, calmed down the tense relations between the two nations and at the same time the loss of the military significance of the Welsh castles. Newcastle Emlyn was acquired in the early sixteenth century by the magnate Sir Rhys ap Thomas, who transformed the castle into a dwelling residence, among others piercing large, rectangular windows.
During the English Civil War, the castle was originally a Royalist stronghold and an early modern bastion for artillery was erected in front of the gate, to raise its defenses. Nevertheless, the castle changed hands several times. In 1644, it was captured by the forces of Parliament, and then quickly recaptured by royalists led by Sir Charles Gerard. The parliamentarians besieged it again in 1645, but unsuccessfully. Only when all of Wales was under the rule of the Parliament, Newcastle Emlyn was also seized, and then unfortunately razed to the ground to prevent its further military use.
The castle was erected on a peninsula and was almost completely surrounded by Afon Teifi waters. The main castle was in the form of a polygon with a shape similar to a triangle. The gate was on the west side and from the mid-fourteenth century it consisted of two polygonal towers flanking the passage between them. Under the north tower there was a vaulted cellar. The upper floor of the gatehouse was accessible via an external staircase on the eastern wall, next to the northern tower. This staircase could also provide access to the sidewalk of defenders on the walls. There were latrines on both sides of the gatehouse. To the south of the gate there was a square tower in the form of a wall projection. Next to it was the building of the great hall and adjacent chapel, kitchen and pantry. The main castle was surrounded by an outer defensive wall separating extensive outer bailey. Economic buildings, including a water mill, were located there. The main gate was placed on the west side, side wicket gate from the south-eastern side.
Only minor relics of castle survived until today, the most magnificent of which is the lower part of the twin-towers gatehouse of the inner ward. Unfortunately, it was additionally distorted by pierced large window openings. The ruin area is open to visitors for free.
