The castle is first mentioned in 1094, when the name Rhyd y Gors is used. The earliest castle, built by the Norman William fitz Baldwin, may have been sited elsewhere perhaps further down the river. After 1105 the annals refer to Carmarthen by name, so by then certainly, the Norman castle was on its present site. The castle evidently became important early on, and passed into the hands of the crown. Carmarthen quickly became the administrative center of south-west Wales, and inevitably underwent a series of attacks and rebuilding episodes during the turbulent struggles between Welsh and English in C12 and C13. Among these episodes was the capture and destruction of the castle by Llywelyn the Great in 1215, after which extensive rebuilding work was undertaken by William Marshal the younger earl of Pembroke, who had re-captured the castle in 1223. It may have been at this period that the massive stone defences were built on the site of the original motte. (James)
Carmarthen Castle is a large and important castle but it has a disputed foundation, originating in 1109 or the late 13th century; remains of the high medieval castle, including a shell keep, gatehouse and two towers, are obscured by modern buildings, notably County Hall. The site was used as the county gaol from the eighteenth century (nprn 100074). See Ludlow 2003 (Carm. Ant. 39), 147-151. J.Wiles, RCAHMW, 15.09.2004. 2. Repairs and additions to castle made throughout the thirteenth to fifteenth centuries. The gaol, designed by John Nash, was located on the east side, within the curtain wall. Extant remains include the motte, donjon with towers, gatehouse, and southwest drum tower. (Source: Cadw listed buildings database) J.Hill, RCAHMW, 04.09.2003. 3
The castle was the site of a siege in 1233-4: In 1233, Richard Marshall, Earl of Pembroke, laid siege to the castle of Carmarthen, which successfully resisted his assaults for three months, when the arrival of succours by sea compelled the earl to abandon his enterprise. Samuel Lewis, A Topographical Dictionary of Wales, 1833. 1233: Maelgwn Fychan ap Maelgwn ap Rhys and Owain ap Gruffudd and Rhys Gryg and their sons and the host of Llywelyn ap lorwerth and the host of the earl of Pembroke gathered together against Carmarthen. And they laid siege to it for three months, and they made a bridge upon the Tywi. And then the sailors came armed, with the tide, to break down the bridge. And when the Welsh saw that their expedition would be fruitless, they returned to their lands. Source: Thomas Jones, The Chronicle of the Princes, 1955, p.233. "towards the end of this year (1233) . . . earl Richard (Richard MarshalI, earl of Pembroke), Rhys Gryg, Maelgwn Fyhan, and Owain ap Gruffydd besieged the fortress (of Carmarthen) for three months and by building a temporary bridge across the river Towy, shut off all hope of relief from . . . the Bristol Channel. . . in March 1234, Henry de Turberville sailed with a fleet from Bristol and . . . broke up the improvised bridge, with great slaughter of its defenders."

Originally a motte and bailey castle, built 1109 by Walter, Sheriff of Gloucester, attacked unsuccessfully by Gruffydd Ap Rhys in 1116, destroyed in 1137, and rebuilt by Gilbert fitz Richard, Earl of Pembroke, in 1145. Re-captured in 1146, it was strengthened by Cadell ap Gruffydd in 1150, returned to English royal control, it was probably first rebuilt in stone, resisting attack by the Lord Rhys in 1190 and 1196, but taken by Llywelyn the Great in 1215. William Marshall the younger retook the castle 1223, and returned it to royal hands after some repairs in 1226. In 1233, it withstood a 3-month siege by Llywelyn, and was not captured when the town was pillaged in 1244 and 1246. In 1248 given to custody of Robert Waleran who is recorded as adding a hall and chamber, and in 1258, after the massacre of an English army from Carmarthen at Coed Lathen in 1257, bestowed on Prince Edward, later Edward I. A survey in 1275 referred to a great tower, 5 small towers, hall, kitchen stable and chapel, all surrounded by a stone wall with one gate, and in need of repair. The castle became the seat of royal government in S Wales with the appointment of Bogo de Knovill as Justiciar of S Wales, 1280. Rhys ap Maredudd pillaged the town but did not take the castle in 1287, the castle was repaired in 1288 for £169/15/3d (£169.76). Repaired and added to in the C14 with very substantial royal apartments and administrative rooms: in the C14 the list included King's hall and chambers, King's chapel, Queen's apartments, Chamberlain's hall, chapel for knights and esquires, Exchequer offices, kitchens, granary, wine cellar, armoury and stables. In 1340 the chamberlain's hall was repaired, in 1355 a wine-cellar made under the hall, and another hall had been added by 1370. A gate and chamber between the 2 wards of the castle had been completed by 1394. The Black Prince was granted the lordship in 1343 and visited in 1351, 1362 and 1370. Richard II visited in 1399. The castle was captured by Owain Glyndwr in 1405, having sacked the town in 1403. In 1409 over £380 was spent on repairs - nearly £100 on rebuilding the gatehouse. Important during the Wars of the Roses, it was granted to Sir Rhys ap Thomas (d 1525) as Chief Justice of S. Wales. During the Civil War, the castle was captured by the Parliamentarians under General Laugharne in 1644, but retaken by Royalist forces. By 1648, Laugharne had changed sides, and Cromwell halted at Carmarthen, probably then ordering the slighting of the castle, described in 1660 as ''quite demolished''. In 1789-92, John Nash's County Gaol was built on the E side within the curtain wall, for which much of the remains were demolished. A section of the original castle collapsed c.1811. The gaol was extended over the years, and covered most of the site. From 1938, the construction of the County Hall obliterated any remains on the gaol site within the curtain walls.
Remains of a rubble masonry castle, mainly C12-C14. Present ruins comprise a stone-revetted motte, twin-towered gatehouse (much altered from a probable 4-cornered gatehouse), a corner tower and wall turret with short sections of curtain wall, all to W of the site. To NW, motte walls have 2 small half-round turrets to N and paired buttresses representing the site of a further turret to W. Heavily repointed and repaired, there is little clear evidence of medieval fabric, the majority of the masonry appearing C19 in date. The curtain wall connecting the motte with the gatehouse is also largely rebuilt. Fine 3-storey rubble masonry gatehouse of c.1400, stylistically similar to Kidwelly Castle, possibly by same mason. Roughly square with paired turrets to façade, flanking large 4-centred gate arch. Gate passage partially blocked internally in C18 as part of gaol. Outer portcullis slot visible. Twin towers with formerly battlemented coping on raised corbel table. The upper floor originally held the constable's chambers and has ashlar traceried trefoil-headed window openings. SW tower possibly late C13, 3 storeys in height with fine angle spur buttresses, rounded exterior and square interior with openings to each storey. Basement has whitewashed interior with chute to SW beneath a 2-centred barrel-vaulted ceiling. SE angle has arched-headed door leading to newel stair access to upper storeys. Modern entrance from the terrace below the castle, inserted following excavation and consolidation in the 1990s. A short section of curtain survives to the east. E of this tower, on the S of the circuit, is the basement of the rectangular Water Tower. The interior is a tall square chamber in whitewashed rubble with a flat stone vault. Narrow openings to each face. S side partly rebuilt in 1960s. (Listed Building Report)
