Gilmerton was a castle that was destroyed in the 16th century and nothing of it now remains.

The lands of were of Gilmarstone granted to Richard de Morville, Constable of Scotland, in 1165, however by the early 14th century they were owned by William de Soules. In 1320 de Soules plotted against Robert the Bruce and his lands were forfeited, with Gilmerton granted to Muireadhach III, Earl of Menteith.

By 1371 Gilmerton was owned by Sir John Herring or Herries and in 1375 the half lands of Gilmerton passed to Sir Walter Somerville of Linton and Carnwath when he married Sir John’s only surviving daughter and heir, Giles.

The castle was burnt by the English in the Rough Wooing of 1547 and left in ruins, however it was seemingly rebuilt and in the 17th century was owned by the Crichtons of Cranston-Riddale. In 1667 Sir John Baird of Newbyth bought Gilmerton from the Crichtons but by 1792 the house was empty as the family preferred to stay at Newbyth.

The site of Gilmerton now falls within a housing estate at the south corner of Gilmerton Place.
