San Marino: Second and Third Tower

On Tuesday I got five postcards from San Marino.

One of them shows the Second and Third Tower, the Cesta and Montale. The Second Tower was built in the 13th century on the highest peak of Monte Titano. Today it houses a museum about Saint Marinus. The Third Tower was built in the 14th century on the smallest peak of Titano. It is the smallest of the three towers and completed the Sanmarinese defence system. It is not open to the public. 

Stamps:
450th birth anniversary of Galileo Galilei (whole set) (issued 22-10-2014)
with a pictorial postmark showing the First Tower

Thank You very much William!
