History
Dundrum Castle is a Norman fortress in the United Kingdom, built after John de Courcy’s invasion of Ulster near the beginning of the thirteenth century. The Normans were a medieval ruling and military elite who established stone castles across parts of Ireland after the late-twelfth-century Anglo-Norman invasion. Dundrum controlled access into Lecale from the west and south, giving it an important position in the region.
John de Courcy and Hugh de Lacy
The castle’s earliest defenses may have consisted of an earth-and-timber enclosure. John de Courcy was expelled from Ulster by Hugh de Lacy in 1203. In 1205, the Chronicle of Mann records de Courcy’s failed attempt to besiege the “castle of Rath” with the help of 100 ships belonging to his brother-in-law, Rǫgnvaldr Guðrøðarson, King of the Isles.
King John captured Dundrum in 1210. Hugh de Lacy subsequently strengthened the fortress with a massive round keep, probably employing master masons from the Welsh Marches, the frontier zone between England and Wales. Dundrum remained Crown property until de Lacy was allowed to return to his earldom in 1226. After his second period as Earl of Ulster, from 1227 to 1243, a twin-towered gatehouse was probably added to the curtain wall.
The Mac Artáin and Magennis periods
The Mac Artáin chiefs of Kinelarty probably built the stone curtain wall around the outer bailey and held Dundrum in the late fifteenth century. After 1333, their Magennis cousins managed the castle, which was sometimes known as Magennis Castle.
Capture, dismantling, and later residence
The Earl of Kildare briefly captured Dundrum in 1517, followed by Lord Deputy Grey in 1538. Phelim Magennis Mac Artáin and his son Donal Oge Mac Artáin surrendered the castle to Lord Mountjoy in 1601. It passed to Lord Cromwell in 1605 and was sold to Sir George Blundell in 1636.
The Mac Artáin clan may later have received the castle again, but Parliamentarian forces subsequently repossessed it. Their garrison withdrew in 1652 and dismantled the fortress. After 1660, the Blundells returned and built a mansion within the outer bailey. The property later passed to the second Marquess of Downshire in the early nineteenth century, by which time the mansion had become ruined. Trees were probably planted on the hill during this period.
The seventh Marquess of Downshire placed Dundrum Castle and its grounds in State Care in 1954. Dundrum is a legally protected State Care Historic Monument and is regarded as an important example of Norman architecture.
Remains
The ruin occupies the summit of a rocky hill above Dundrum. Its elevated position overlooks Dundrum Bay and the Mourne Mountains to the south, Slieve Croob to the west, and the plains of Lecale to the east. The surviving complex includes the upper and outer ward defenses, a round keep, a gatehouse, and the remains of a later mansion.
Upper ward defenses
Curtain wall
A stone curtain wall, an enclosing defensive wall, surrounded the upper ward and was probably built at the beginning of the thirteenth century. Covered walks along the outer wall-head helped defenders move around the enclosure. A double latrine is incorporated into the wall, and an early timber hall may have stood near the keep.
Round keep
The massive round keep was built for Hugh de Lacy and originally rose at least three storeys. A surviving fireplace flue and spiral stair indicate its former height. Much of the second floor was rebuilt in the fifteenth century. The basement was used for storage and included a cistern, a tank for storing water, below the first floor. The first floor appears to have contained the great chamber, the principal living and reception room of the lord, while the level above probably held his private chamber.
Twin-towered gatehouse
The twin-towered gatehouse was inserted into the curtain wall, probably after Hugh de Lacy’s second tenure as Earl of Ulster. Its design is lopsided, with one projecting tower protecting the approach along a narrow ramp from the south-west. The arrangement has been compared with the gatehouse at Pembroke Castle.
Outer bailey and later mansion
The outer bailey, an additional enclosed area outside the principal ward, was surrounded by a stone curtain wall probably built by the Mac Artáin chiefs. After 1660, the Blundells constructed a gabled, L-shaped mansion in its south-west corner. The mansion was ruined by the early nineteenth century, and its remains form part of the later history of the castle complex.
