Ronaldsway (Manx: Roonysvaie) is a settlement in the parish of Malew in the south of the Isle of Man, between the village of Ballasalla and the town of Castletown.
It is notable as the location of Isle of Man Airport and historically of RNAS Ronaldsway, together with the adjoining customs free zone and industrial estate.
Ronaldsway first appears on record in the Chronicle of Mann, which documents an instance when Rǫgnvaldr's half-brother, Óláfr (died 1237), landed on the island in 1224, and confronted him for a share of the kingdom.
[1] While the airfield runway at Ronaldsway Airport was being extended during the Second World War, a sunken-floored structure was uncovered dating from the third millennium BC in the late Neolithic era.
The distinctive nature of the finds, including pots and stone tools, gave rise to the name Ronaldsway culture, and similar artefacts have been found elsewhere.
