Edinburgh is a city with many attractions and is renowned for its annual Edinburgh Festival, the biggest festival of live events in the world. During the festivals the city's population doubles. Another thing is that Edinburgh is the second most visited city in the UK after London with around 13 million tourists per year.
The historic center of Edinburgh is divided into two large green areas by the Princes Street Gardens. To the south the landscape is dominated by Edinburgh Castle, sitting on the extinct volcanic plug that is Castle Rock, and the long strip that Old Town is aiming for its edge. To the north lies Princes Street and New Town. The gardens were made in 1816 in what had been the Nor 'Loch. To the west of the castle lies the financial district, housing insurance and banking buildings. Probably the most exciting building, with its large circular building made in sandstone, is the International Conference Center in Edinburgh.
