Fortezza Medicea di Arezzo
At the top of Colle di San Donato, Arezzo's Medicean fortress sits in a state of deliberate openness — its star-shaped walls, once designed to keep people out, now draw them in for the view alone. From the bastions, the Arno valley spreads below and the Pratomagno ridge fills the horizon.
The fortress is a public garden now, free to enter, and locals treat it accordingly — morning walkers, kids on bikes, the occasional reader on a bastion wall. Beneath the grass, excavations uncovered the remains of an 11th-century church and a Roman-era mosaic, layers the 2016 restoration quietly brought back to light.
💛 What travellers fall for
People who return tend to time it for late afternoon, when the light on the valley is softer and the crowds have thinned. The Belvedere bastion gives the clearest sightline north. Worth a slow loop of all five bastions — each has a slightly different angle on the city below.

A fortified presence has stood on this hill since the 9th or 10th century. The 14th-century bishop-count Guido Tarlati built a keep here, of which only the Porta Sant'Angelo survives. The current structure was commissioned in the early 16th century to the Florentine architects Giuliano and Antonio da Sangallo, with Antonio da Sangallo the Younger responsible for the distinctive five-bastion star plan; Grand Duke Cosimo I de' Medici oversaw its completion around 1540.
French troops attempted demolition in the early 19th century — the scarring on the western wall is still visible. Count Vittorio Fossombroni purchased the ruin in 1816 and eventually bequeathed it to the city of Arezzo in 1893. Restoration between 1896 and 1904 converted it into a public garden, and a second major restoration completed in 2016 revealed the buried church remains and Roman mosaic.

When to go
Spring (April to June) and early autumn (September to October) offer the most comfortable walking conditions, with clear sightlines across the valley. Summer visits are best made in the early morning or around dusk, when the hilltop heat eases and the light is worth the climb.
