Edinburgh is one of Europe's most beautiful cities, draped across a series of rocky hills overlooking the sea. It's a town intimately entwined with its landscape, with buildings and monuments perched atop crags and overshadowed by cliffs - in the words of Robert Louis Stevenson, 'a dream in masonry and living rock'. From the Old Town's picturesque jumble of medieval tenements piled high along the Royal Mile, its turreted skyline strung between the black, bull-nosed Castle Rock and the russet palisade of Salisbury Crags, to the New Town's neat grid of neoclassical respectability, all columns and capitals, porticoes and pediments, the city offers a constantly changing perspective. And it's all small enough to explore easily on foot.
