Known as the "pearl of Valdichiana",[4] Lucignano is a remarkably conserved medieval walled hill-top village (400 meters above sea level), elliptical in shape.

Its altitude and strategic position on the road between Siena and Arezzo meant that between 1200 and 1500 it was continually the subject of battles between these cities, involving also Florence and Perugia.

Once the town came under the rule of Florence, construction began of the fortress, attributed to Bernardo Puccini.

Sights include: Of note is the elaborate reliquary made for the church of San Francesco, which is now in the Museo Civico, on the ground floor of the 13th Century town hall (Italian: Palazzo Pretorio).

[4] The tree is gilded and bejeweled and is signed by two jewellers, Ugolino di Vieri in 1350 and Gabriello D'Antonio in 1471.
