San Marino: Three Towers

On Tuesday I got five postcards from San Marino.

One of them shows the Three Towers of San Marino. The Three Towers are a group of towers. They are located on the three peaks of Monte Titano. The towers are shown on San Marino's national flag and coat of arms.

Stamps:
3D Printing Revolution (from set of three) (issued 10-03-2015)
Fight against gender-based violence (from set of four) (issued 17-03-2014)
International Year of sustainable energy for all (from set of four) (issued 09-05-2012)
with a pictorial postmark showing the First Tower

Thank You very much William!
