The King's Stables is an archaeological site in County Armagh, Northern Ireland.
The earthwork known as the King's Stables is a Scheduled Historic Monument in the townland of Tray, in Armagh City and District Council area, at grid ref: H8388 4546.
[1] It consists of a boggy hollow, originally an artificial, flat-bottomed pool about 25 metres (82 ft) in diameter, partly surrounded by an earthen bank, about 300 metres (985 ft) north-east of Haughey's Fort.
Excavations in 1975 discovered clay moulds for bronze leaf-shaped swords, pottery, and items of worked bone and wood.
The name is probably related to a local tradition that the ancient kings of Ulster watered their horses and washed their chariots in the pool.
