west end of The Cross is The Ell Shop (NTS), built 1757, which takes its name from the iron ell (weaver's measure) fixed against one corner. This building is said to have been built on the site of the town's medieval hospital, dedicated to St George. At the north-west corner of the same row is the Duchess of Atholl Girls' School, erected 1853 in neo-Gothic style, designed by R & R Dickson. It is generally known as the Duchess Anne after its founder Anne Home-Drummond (1814–97), spouse of the 6th Duke of Atholl and Mistress of the Robes to Queen Victoria. The building is used for exhibition and other purposes, notably the popular annual Dunkeld Art Exhibition in summer. The left arm of the 'Y' leads along Cathedral Street to the medieval cathedral, and the right arm (now largely blocked off) originally led to Dunkeld House, built by Sir William Bruce in 1676-84 for the 1st Marquis of Atholl. Demolished in 1827, this was one of Scotland's major 17th-century mansions. A neo-Gothic replacement was begun on the same site but never completed (no visible remains). The area around the cathedral was the original focus of settlement in Dunkeld in medieval (and doubtless earlier) times. Here stood the manses of the Cathedral clergy, with the Bishop's Palace to the west of the church. Surrounding countryside Dunkeld is situated in an area of Scotland marketed as Big Tree Country. The area is heavily wooded, and has some notable trees, including the Birnam Oak, believed to be the only remaining tree from the Birnam Wood named by Shakespeare in his play Macbeth: Other significant trees in the area include Niel Gow's Oak, the tree under which Niel Gow, a fiddler under contract to three of the Dukes of Atholl, composed many of Scotland's famous strathspeys and reels. It stands near Gow's home at Inver. The Parent Larch near Dunkeld cathedral is the sole survivor from a group of larches collected from the mountains of the TyroNiel Gowl mountains in 1738, and which were the seed source for large-scale larch plantings in the local area. Much of the countryside surrounding the town is designated as a national scenic area (NSA), one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection by restricting certain forms of development.
