Markle Castle

Óengus II is reputed to have rested his army in this area before the battle in 832 at which the Cross of St Andrew was said to have appeared. On the same day, Haddington, Stenton, "Bentestoun" (Stevenson), and Prestonpans were burnt. By 1588, Markle was shown as a Clan Stewart property in the Register of the Great Seal of Scotland; the last reference to it in the register is for 1635. In November 1600, Robert Hepburn was resident at the "Place of Markle" when his kinsmen abducted Margaret Carkettle from Monkrigg (near Lennoxlove) and brought her to Markle, treating her in "abominable and destable form".

A few fragments of the walls of Markle remain on a rocky mound. The remains of the 14th century tower house forms a courtyard with the 16th-century hall. There was once a fortified ditch. There were monastic buildings of which no traces remain.
