Caldwell Castle, Category A listed castle in East Renfrewshire, Scotland.
Caldwell Castle is a three-storey rubble-stone tower standing near the Lugton Water in East Renfrewshire, Scotland. Its walls are notably thick, which is typical of Scottish tower houses built for defense in exposed rural locations.
The Mure family came to own the estate in 1328 through a marriage alliance, with Sir Reginald Mure among the earliest recorded holders. The tower remained in family hands across many generations, which helped shape the local history of this part of East Renfrewshire.
The Mure family name is still tied to this corner of East Renfrewshire, and the tower stands as a reminder of how landed families shaped rural Scotland. Visitors who walk around the exterior can read the landscape as it once was, with the tower at the center of a working estate.
The tower can be reached via Gleniffer Road B775 and sits just south of Caldwell Crossroads. Only the exterior is accessible, so a walk around the building gives the best sense of its scale and stonework.
The estate once included an underground icehouse, which was used to store ice collected from the Lugton Water nearby. This allowed the household to keep food fresh throughout the year, long before refrigeration existed.
