Hilly Edinburgh, Scotland's capital, has a medieval Old Town and an elegant Georgian New Town, with gardens and neoclassical buildings. It's home to Arthur’s Seat, an extinct volcano in Holyrood Park with sweeping views from its peak. Looming over the city is hilltop Edinburgh Castle, home to Scotland’s crown jewels and the Stone of Destiny, traditionally used in the coronation of Scottish rulers. The most recent official population estimates are 464,990 2014. Winter daytime temperatures rarely fall below freezing, summer temperatures are normally moderate, rarely exceeding 22 °C (72 °F). The city hosts the annual Edinburgh International Festival, which is one of many events that run between the end of July and early September each year. The best known of these events are the Edinburgh Festival Fringe, the Edinburgh International Festival, the Edinburgh Military Tattoo and the Edinburgh International Book Festival. The annual Edinburgh Hogmanay celebration was originally an informal street party focused on the Tron Kirk in the High Street of the Old Town. Since 1993 it has been officially organised with the focus moved to Princes Street.
