The East Quarter, apart from its courtyard façade is ruined. The centrally placed access tower, the Crosshouse, was reconstructed by the Marquis of Bute. The National Trust's architect, Schomberg Scott recreated the King and Queen's bedchambers within. The northern section of the East Quarter was originally a lodging built by James IV. The East Quarter was remodelled by the mason John Merlioun in 1538. This part of the building, with its "back galleries" overlooking the garden was decayed in 1615. In 1616 the master of works, James Murray was ordered to repair the flat roof of the King and Queen's galleries and the roof of the lodging of the East Quarter in anticipation of the visit of James VI.
