Most visitors to San Marino choose to explore the ancient fortresses and battlements located on the top of Mount Titano, which overlooks the city with its ancient and modern property San Marino. There are three main towers: La Rocca (First Tower), the Cesta (Second Tower) and the Montale (Third Tower). La Rocca, dating from the 11th century, was carved directly out of the stone of the mountain and boasts a glorious bell tower. The 13th century Cesta is the highest of the three towers and contains the San Marino Museum of Antique Weapons. The Montale is also of the 13th century. The First Tower is limited by two circles of defensive walls. The inner ones, adorned with merlons and braced on the corners with angular towers, subsequently lowered during the 16th century, belonged to the first wall circle (Guaita Wall Circle), which was built to defend the inhabited area. The first Tower Guaita, rises at the same time to crystallizing itself of the communal conscience. It discouraged the attacking ones while the reputation was already run. Welcome from Imola defined it "mirabile fortilitium". To the shelter of the solid structure of the guaita one, the people, ignoring every stranger to be able, acquired knit conscience of means with which to conserve its autonomy at first embezzling itself to the soggezzione of the most powerful neighbors and in a second phase to the ecclesiastical jurisdiction.
