Walls of Grosseto

The Walls of Grosseto (mura di Grosseto), known also as Medicean Walls (mura medicee), are a series of defensive brick walls surrounding the city of Grosseto in southern Tuscany, Italy.

The fortifications were commissioned by Cosimo I de' Medici, after the conquest of the Republic of Siena and its annexation to the Grand Duchy of Tuscany. The walls were designed by engineer-architect Baldassarre Lanci in 1564. Construction began in 1565 and was completed in 1593.

During the 19th century, under the rule of Leopold II, the walkways of the walls were demilitarized and transformed into gardens and promenades.
