Inside the castle of Monteriggioni, a fortress built by the Sienese at the beginning of the 13th century, it is possible to visit the circuit which includes the walkways on the city walls and the educational path "Monteriggioni in Arme". The walkways on the walls were built in the early 2000s and consist of two distinct walkways of different lengths, located near the gates of the village. The routes ideally reproduce a medieval patrol path, which may have also existed in Monteriggioni in the past.

From the two walkways it is possible to observe the castle from a privileged position, but also enjoy a breathtaking panorama, which ranges from the Chianti hills to the Montagnola woods, up to, in the distance, the towers of San Gimignano. The “Monteriggioni in Arme” educational path, with access from Piazza Roma 23, is divided into four rooms, which retraces the period in which Monteriggioni functioned as a military outpost of the Republic of Siena.

Each room, dedicated to a different century between the 13th and 16th centuries, contains reproductions of weapons and armor presumably in vogue in the area and bilingual panels that illustrate local history and the siege and defense techniques of a medieval castle. The pieces on display were created respecting ancient techniques, referring to original elements if existing and to contemporary depictions of soldiers and battle scenes. Particularly appreciated is the possibility of handling and wearing some parts of armour, which offers the public a direct interaction with the exhibition, making it an active part of the educational journey (this activity is currently suspended due to the health emergency).
