Prominent to the south east is the Salisbury Crags teschenite sill and the vents and lava flows of the Arthur's Seat volcano, of which Calton Hill is a faulted fragment (Arthur's Scat Excursion). Ice erosion moulded these crags into their present form, just as it sculpted the crag and tail which forms the head and backbone of the Old Town (Castle Hill Excursion), where this walk started.

	The former Royal High School building. begun in 1825 as a replacement for the original school in High School Yards in the Old Town, and more recently adapted for use of the proposed Scottish Assembly, is built ~~ofCraigleith~~ Sandstone. Many other buildings on the Calton Hill are built of the same stone, including Observatory House (1792), the Nelson Monument (1816), the City Observatory (1818) and Playfair's Monument (1827). Most impressive of all is the incomplete National Monument to the Scottish Dead of the Napoleonic War. Started in 1823, work was abandoned in 1829, though ~~severalluter~~ plans were put forward for its completion. Part of a ~~particulurly~~ large stone, dug out of Craigleith Ouarry soon after work on the monument began, went to the architrave; the rest of this stone went to Buckingham Palace. The twelve pillars are ~~mude~~ of the commoner of the two types of freestone from Craigleith laid on its ~~naturul~~ bed. The Dugald Stewart Monument (1831) is built of light yellow Humbie freestone from West Lothian, ~~ulso~~ used for the Burns Monument (1830) across Regent Road. Extensive refacing of the latter monument in 1978 has meant that it is now almost all Darney stone that is seen there.

	Descent of the Playfair Steps gives access to two very important and recently cleaned buildings at the foot of the Mound.

Descent of the Playfair Steps gives access to two very important and recently cleaned buildings at the foot of the Mound. Both the more austere National Gallery and the Royal Scottish Academy to the north were designed by the architect William Playfair.

	The National Gallery (begun in 1850) is built of Binny Sandstone brought the 20 km to Edinburgh by the Union Canal (opened 1822) which passed only 3 km from the main quarry near Uphall. Binny stone was fairly easy to work when fresh from the quarry but soon hardened on exposure to the air. It was ~~s<lid th<~~that a stone-worker could chisel 15 linear feet of Binny stone in the time it took him to dress 6 feet of Craigleith stone. Iron content produced the orange colour of Binny stone while bitumen gave it a freckled appearance and was believed to increase its durability. Ripple-marking and cross-bedding can be seen in the large polished ashlar blocks.

Iron content produced the orange colour of Binny stone while bitumen gave it a freckled appearance and was believed to increase its durability. Ripple-marking and cross-bedding can be seen in the large polished ashlar blocks.

	The Royal Scottish Academy was built as the Royal Institution in two stages. The original building (1822-6) is a mixture of polished Craigleith stone and Cullalo sandstone from Fife. The Board of Trustees for Manufacturers and Fisheries who held the feu accepted the lowest of five estimates which depended on the use of the softer, cheaper Cullalo stone, but harder, more expensive Craigleith stone had to be used when the Fife Quarry was unable to produce enough good quality stone. In extending the building(1831-6) Playfair doubled the columns in each colonnade, elaborated the porticos at north and south ends and added a second row of columns and decorative detail to the Princes Street end pediment. This newer work, which stands out in the cleaned building, probably used Binny stone. The eight sphinxes carved by Sir John Steell and the statue of Queen Victoria seated in the robes of Britannia are known to be in this stone. Twice in its 150 years history the Royal Scottish Academy building has suffered failure of the wooden piles used as foundations on the 'mound' of earth. First in 1898 the north-west corner was affected. and in 1909 the north-cast corner, leaving the edge of the roof on the west side looking uneven.

Large bivalve shells cn be seen even from street level.

	The Standard Life Assurance building (1901) has a large frontage on the corner with the north side of George Street. built of a pale yellow sandstone. polished at ground level. rusticated up to the first cornice and polished above that. The stone is likely to have come from Northumberland and the newer part of the building fronting the square has a sandstone facing, perhaps from Blaxter.

	The National Portrait Gallery (1890). reached down North St. Andrew Street. was the first large building in Edinburgh to use New Red Sandstone. quarried from Moat near Carlisle and Corsehill at Annan. The main walls are in regular. coursed. rock-faced rubble. while the flanking buttresses. window dressings and doors are of polished ashlar in which dune-bedding can be seen. The paired windows on the first floor level have grey coarse-grained granite pillars in the arches. The red sandstone has suffered from erosion and has been necessary to remove the corner spirelets. The restoration. due to be completed by 1991. includes rebuilding the spirelets using red sandstone saved from a former Caledonian Railway viaduct in Leith and from the specially re-opened Corsehill Quarry.

	Dundas House (1774). now head office of the Royal Bank of Scotland, was built of Hailes Sandstone from Redhall Quarry as a private house for Sir Laurence Dundas. A feature of this house is the remarkable domed ceiling over the main concourse of the bank. Outside. on the right of the building, weathering has picked out cross-lamination in the sandstone.

	Robert Adam's Register House was begun in 1774. After careful examination of local building stones. Adam chose Craigleith Sandstone and Hailes Sandstone. Interruptions owing to cash shortage and the Napoleonic War delayed completion until 1834 by which time Binny Sandstone was in vogue. Cleaning in 1969 has revealed the yellowish appearance of the latter stone. The ashlar is rusticated to first floor level and polished above. Extensions in 1882 used sandstone from Longannet in Fife.

	The Governor's House is the only part of the old Calton Gaol still standing. It was built of Hermand sandstone from the Upper Oil Shale Group in West Lothian. St. Andrew's House, on the site of the rest of the Calton Gaol. was completed just before the Second World War. by which time little stone was quarried in Edinburgh. It was cheaper to transport polished sandstone from Darney as facing panels for this steel-framed building. Darney blends with other Edinburgh monuments and buildings and is resistant to grime. Fine light grey Creetown granite was chosen from the walls along Regent Road and for the mullions of the main staircase windows. Black Bon Accord granite was used for decorative work at other entrances and windows.		The Governor's House is the only part of the old Calton Gaol still standing.
