Talinn, Estonia, Russia
Firstly, I know Tallinn is Estonia not Europe but for some reason I could not select Estonia as a country to file my postcard. Never mind. Also the pic is of St Petersburg so I will update that soon too.
Anyway Tallinn. Beautiful old city of Europe with lots of cobbled streets, old cathedrals, archways and winding streets surrounded by the old walls.
I spent two days just meandering around the streets observing the view, ducking under huge archways ...
