On Tuesday I got five postcards from San Marino.
One of them shows the First Tower, the Guaita. The First Tower is the oldest and most famous of the Three Towers of San Marino. It was built in the 11th century and was rebuilt to its current form in the 15th century, after it was rebuilt various times. It was considered as impenetrable.

Thank You very much William!
