They've been putting up a Christmas tree in the Tallinn town square since 1441, making it the oldest such display in the world. In recent years, the annual Christmas market that surrounds it has picked up plenty of accolades, and when it's covered in snow, it's surely one of the most idyllic in all of Europe. Be sure to try the local cabbage for a true Estonian experience.
