The Great Hall in Edinburgh Castle is a popular part of the castle, with visitors milling around throughout the day.

Here’s some info about the hall that I got from Perplexity. Sources are linked and makes for an interesting read. I was surprised it didn’t mention that Oliver Cromwell preserved the roof when he had it plastered over. That was something the guide mentioned.

History of the Great Hall in Edinburgh Castle

The Great Hall at Edinburgh Castle is a remarkable structure completed in 1511 for King James IV of Scotland.236 This medieval wonder measures 29 by 12.5 metres (95 by 41 ft) and served as the chief place of state assembly within the castle.5 While historians have occasionally disagreed about its exact dating, it is generally attributed to the early years of the 16th century during James IV’s reign.5

Architectural Features

The hall’s most distinctive feature is its magnificent wooden roof, considered one of the most superb in Britain.236 It features giant beams resting on stones carved with heads and symbols such as the thistle, a national badge of Scotland.236 This is one of only two medieval halls in Scotland that still retains its original hammerbeam roof.5 The decorative carved stone corbels supporting the roof display Renaissance detailing comparable to works at Blois, France, from around 1515, indicating that Scottish arts were relatively advanced for the time.5

Historical Timeline

James IV had little opportunity to enjoy his new grand hall, as he was killed just two years later at the Battle of Flodden in 1513, fighting against the forces of his brother-in-law, King Henry VIII of England.236

During its early years, the Great Hall hosted grand banquets and state events, though there is no evidence that the Scottish Parliament ever met here, despite some common misconceptions.2356

A significant change came in 1650 when Oliver Cromwell’s army captured Edinburgh Castle and began transforming the Great Hall into a military barracks.2356 By 1737, the hall was subdivided into three storeys to accommodate 312 soldiers.5

Following the construction of New Barracks in the 1790s, the Great Hall was converted into a military hospital.5 It continued in this function until the troops finally left in 1886/1897 (sources vary slightly on the exact date).2356

After its military use ended, the Great Hall was restored to its medieval splendour by architect Hippolyte Blanc, who worked according to contemporary Victorian ideas of medieval architecture.5 Today, the hall displays weapons and armour that reference its military past, including distinctive pole arms like the feared Lochaber axe.236

In modern times, the Great Hall is still occasionally used for ceremonial occasions and has served as a venue for BBC Scotland’s Hogmanay Live programme.5
