Scotland's capital likes to draw on its history -- with good reason. It's also launched more than its fair share of notable figures onto the world stage: Sir Walter Scott, Robert Louis Stevenson, Sir Arthur Conan Doyle and Alexander Graham Bell, to name just a few. Old Town reverberates with the history of Scottish royalty and romantic literary figures, while crossing Princes Street into New Town is like passing through a time warp to the 1700s. But the city isn't just wrapped up in history. Tourists flock to the city every summer to partake of the extraordinarily vibrant atmosphere of the Edinburgh International Festival -- it's the world's biggest performing-arts festival. Other cultural festivals coincide, making the festival season the busiest tourist season.
