Talinn - 2011 European Capital of Culture
Talinn is a beautiful city so I'll add another reason to visit as it's next years European Capital of Culture. The Estonian are a singing nation and have performances of choirs up to 30,000 strong. Music will be a strong theme. but how about knitting graffiti.
Just to add to the fun, they have their own Catherine Hill and it's an artists' quarter - lots of studios (not as long nor as steep as ours).
