Edinburgh Castle
The fortress on the volcanic plug at the west end of the ridge. The shape of the whole city follows from this rock: a glacier split around the hard basalt and left a long slope of softer material trailing east behind it. The Royal Mile runs down that tail. Geologists call the formation crag and tail, and Edinburgh is the textbook example.
The Royal Mile
The street running down the glacial tail from castle to palace, with narrow closes dropping away on both sides. Those closes are steep because the ground is. Before the New Town, most of Edinburgh's population lived stacked in tenements along here, aristocrats and labourers in the same stair at different heights, which was unusual anywhere in Europe.
Princes Street Gardens
The green valley between the two towns, and formerly a body of water. The Nor Loch was Edinburgh's defensive northern edge and also where the city put its sewage. Draining it from 1759 was the precondition for building the New Town at all. The gardens are a filled-in cesspit with very good views.
The New Town
James Craig's grid of 1767: three parallel streets, two squares, and a deliberate rejection of everything the Old Town was. Craig was 26 and effectively unknown when he won the competition. The layout was a statement about Enlightenment rationality, and the fact that Princes Street is built on one side only was so the money looking out of the windows had a view.
Arthur's Seat
An extinct volcano inside the city boundary, climbable in an hour from the end of the Royal Mile. It is genuinely a mountain in the middle of a capital. The rock formations here helped James Hutton work out that the Earth was vastly older than anyone had assumed, which makes this hill a founding site of modern geology.
Calton Hill
The hill east of the New Town, covered in neoclassical monuments including one that stops abruptly after twelve columns. The National Monument was meant to reproduce the Parthenon as a memorial to the Napoleonic wars, ran out of money, and has stood unfinished since 1829. Locals have called it Edinburgh's Disgrace for nearly two centuries.
Greyfriars Kirkyard
A graveyard in the Old Town, now visited mostly for a small dog and for surnames that appear in the Harry Potter books. Its harder history is the Covenanters' Prison at the back, where hundreds of prisoners were held in the open in 1679. The tourist version and the actual version of this place have very little to do with each other.
Scott Monument
A 61-metre Gothic spire over a seated statue of Walter Scott, blackened by two centuries of soot and never cleaned, because the stone would be damaged by it. You can climb the inside up a staircase that narrows severely near the top. It is the largest monument to a writer anywhere.
The Scottish Parliament
Enric Miralles's building at the foot of the Royal Mile, opened in 2004 at roughly ten times its original budget and years late. It is genuinely divisive and it is also award-winning. The design deliberately sits low against the crags behind rather than asserting itself, which was read by critics as either humility or timidity.
Dean Village
A former milling settlement on the Water of Leith, ten minutes from Princes Street and almost entirely missed by visitors. Grain was milled here for centuries before the New Town existed. The walkway along the river runs for miles and is the fastest way in the city to stop being in a city.
