Edinburgh is our permanent base of operations, a city renown for its attractive scenery and historical architecture. With its Old Town and Georgian New Town listed as UNESCO World Heritage sites, there is no shortage of inspirational qualities within this 'gothic' city. As the capital of Scotland, Edinburgh has over half a million inhabitants, making it the seventh-most populous city in the UK, yet it still remains one of Britain's greenest cities, with numerous parks and green spaces. A physical representation of the Enlightenment period in Scotland. When scientists, artists, philosophers, designers, writers, economists and others worked alongside, bouncing their ideas off each other.
