thought to have been completed in the early years of the 16th century. The decorative carved stone corbels supporting the roof have Renaissance detailing, which has been compared to works at Blois, France, of around 1515, indicating that the arts in Scotland were relatively advanced at this time. It is one of only two medieval halls in Scotland with an original hammerbeam roof. Following Oliver Cromwell's seizure of the castle in 1650, the Great Hall was converted into a barracks for his troops; and in 1737 it was subdivided into three storeys to house 312 soldiers. Following the construction of the New Barracks in the 1790s, it became a military hospital until 1897. It was then restored by Hippolyte Blanc in line with contemporary ideas of medieval architecture. The Great Hall is still occasionally used for ceremonial occasions, and has been used as a venue on Hogmanay for BBC Scotland's Hogmanay Live programme. To the south of the hall is a section of curtain wall from the 14th century with a parapet of later date. Queen Anne Building In the 16th century, this area housed the kitchens serving the adjacent Great Hall, and was later the site of the Royal Gunhouse.

It was designed by Captain Theodore Dury, military engineer for Scotland, who also designed Dury's Battery, named in his honour, on the south side of the castle in 1713. The Queen Anne Building provided accommodation for Staff Officers, but after the departure of the Army it was remodelled in the 1920s as the Naval and Military Museum, to complement the newly opened Scottish National War Memorial. The museum later moved to the former hospital in the western part of the castle, and the building now houses a function suite and an education centre. Scottish National War Memorial The Scottish National War Memorial occupies a converted barrack block on the north side of Crown Square. It stands on the site of the medieval St. Mary's Church which was rebuilt in 1366, and was converted into an armoury in 1540. It was demolished in 1755, and the masonry reused to build a new North Barrack Block on the site. Proposals for a Scottish National War Memorial were put forward in 1917, during the First World War, and the architect
