Situated in Scotland's Central Belt, Edinburgh lies on the Firth of Forth's southern shore. The city centre is southwest of the shoreline of Leith and inland, as the crow flies, from the east coast of Scotland and the North Sea at Dunbar. While the early burgh grew up near the prominent Castle Rock, the modern city is often said to be built on seven hills, namely Calton Hill, Corstorphine Hill, Craiglockhart Hill, Braid Hill, Blackford Hill, Arthur's Seat and the Castle Rock, giving rise to allusions to the seven hills of Rome.
