The Thistle Chapel is a 1909 addition to the cathedral. It was designed in a neo-Gothic style. The chapel serves as an annual meeting point for the members of the Order of the Thistle, a chivalric order founded in 1687 by king James VII of Scotland, and II of England.
The Order of the Thistle, for whom this chapel was built, is the highest honour available in Scotland and the second highest in the country after The Order of the Garter.
The Order of the Thistle is a Scottish order of chivalry, second only to the Order of the Garter. There are sixteen Knights and Ladies, and currently three Extra Knights and Ladies.
There is a service for the order held in the chapel once a year around June or July when the Queen is staying at Holyrood Palace read more
