Tallinn, Estonia Tallinn’s old town easily is a UNESCO World Heritage Site, and seems to be the place to be if you’re into ‘old towns’ like me. I read that Tallinn is also a good ‘walking’ city, which suits me to the ground, as I like to get about on foot. Now that Henry is up and walking, perhaps we can go walking through the town together! It also serves as a useful ferry point to a few other places that I'd like to visit.
