Ochiltree Castle, West Lothian

[3] The estate was owned by Sir James Hamilton of Finnart between 1526 after the forfeiture of Stirling of Keir and his beheading for treason in 1540.

Its history after that date is unclear, but it may have been owned in the late 16th century by Captain James Stewart of Ochiltree in East Ayrshire who may also have built it.

[3] The entrance was originally in the interior angle in the north wall, adjacent to the circular stair turret.

About 1610 it was extensively remodelled with a new doorway in the western face that opened on a porch; two finialed pediments over the doorway display the monograms of Sir Archibald Stirling of Keir and his wife Dame Grizel (née Ross) Stirling.

[6] A new west range of two-storey offices was also added, although this was later replaced in the late 19th century with a long single-storey wing, probably incorporating parts of the previous structure in its southern wall, with one block projecting south east.
