The postcard shows Tallinn, the capital of Estonia. The old town of Tallinn is in the list of UNESCO Heritage Sites. I assure you it is worth visiting. There are a lot of interesting places like the St Catherine's passages featured in the postcard below.

And this postcard (also sent by Mart) is really special because it inspired one of my trips (three years ago). As it had happened with Croatia! This is Kõpu lighthouse, in the Estonian island of Hiiumaa. It is one of the oldest lighthouses in the world, having been in use since 1531. Quite impressive! The stairs of this lighthouse are really different from the rest of lighthouses I've visited.
