Internally, the Palace comprises two apartments, one each for the king and queen. Each has a hall, presence chamber, and bedchamber, with various small rooms known as closets. The Renaissance decoration continued inside, although little has survived the building's military use, excepting the carved stone fireplaces. The ceiling of the King's Presence Chamber was originally decorated with a series of carved oak portrait roundels known as the Stirling Heads, described as "among the finest examples of Scottish Renaissance wood-carving now extant." Some of the heads may have been made by a French-born carver Andrew Mansioun. The carvings were taken down following a ceiling collapse in 1777, and of an estimated 56 original heads, 38 survive. Most were given to the Smith Institute in Stirling but now these are preserved in the castle, and three more are in the National Museum of Scotland, Edinburgh. Another two are on display in the Thieves Pot, a preserved 16th-century jail within the Thistles Shopping Centre.
