Mura Medicee di Grosseto

Grosseto's Medici Walls form a nearly complete hexagonal circuit around the historic centre. Built in the sixteenth century and later converted into a tree-lined promenade, the fortifications preserve gates, bastions and the older Cassero Senese.

Why it matters

The walls are among the best-preserved examples of a Renaissance fortified city in Tuscany. Their six bastions and connecting curtain walls reflect the Medici transformation of Grosseto into a frontier fortress after the conquest of Siena's territory.

What to notice

Porta Vecchia preserves an earlier medieval tower, while the Bastione Maiano belongs to the first phase of the Medici works. At the Bastione Molino a Vento, the former windmill site is now a garden. The Bastione Fortezza gathers the Cassero Senese, parade ground and chapel of Santa Barbara within the fortified complex. Artillery galleries survive beneath parts of the circuit.

Context and history

Grosseto's medieval defences were repeatedly rebuilt. The Medici works began in 1565 under Baldassarre Lanci and continued into the 1590s. Under Leopold II, the guard posts were removed in 1855 and the ramparts were planted as a public promenade. Restoration campaigns since the late twentieth century have recovered parts of the Cassero and the underground galleries.
