The New Town is a central area of Edinburgh, the capital of Scotland. It was built in stages between 1767 and around 1850, and retains much of its original neo-classical and Georgian period architecture. Its best known street is Princes Street, facing Edinburgh Castle and the Old Town across the geological depression of the former Nor Loch. Together with the West End, the New Town was designated a UNESCO World Heritage Site alongside the Old Town in 1995.
