The Guaita fortress is the oldest of the three towers constructed on Monte Titano, and the most famous. It was built in the 11th century and served briefly as a prison. It is one of the three towers depicted on both the national flag and coat of arms. It was registered as one of the World Heritage Sites in 2008.
Guaita was rebuilt in the second half of the 15th century and in the 16th century has been covered with a sloping roof. It is called the Rocca Guaita and, within its solid walls, protected by double walls (the external wall with merlons and truncated towers at the corners), the population found refuge during sieges.
The upper entrance door, which can be reached by a staircase, is protected by a small wooden construction of 1481. The courtyard contains some pieces of artillery from the Second World War: two mortars, a gift from Vittorio Emanuele II, two 75mm canons fired by the Guardians of the Rocca during national festivities, a gift of Vittorio Emanuele III.

It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
