Murieston Castle had become ruinous by the early 19th century, when it was restored in the 1820s or 1830s. It has been described as being over-restored, and having the character of a folly. The restoration was for John Keir who bought Wester Murieston in 1819.
The castle was oblong, the walls being of rubble, two storeys high. At first-floor level there is roofless turret, corbelled out in the original building. The tower is about 7 metres long, running north-west to south-east, and 5 metres broad.
