[3][4] Murieston Castle had become ruinous by the early 19th century when it was restored around 1824.

[5] The restoration was for John Keir who bought Wester Murieston in 1819.

At first-floor level there is a roofless turret, corbelled out in the original building.

A double doorway carries a medallion with arms in spandrel, dated 1824.
