Why go
The fortress makes the aftermath of Siena's defeat by Florence visible in stone: Cosimo de' Medici ordered it after the republic fell. Today the tree-lined ramparts offer a quieter way to look back toward the city and surrounding hills. It is most useful when you want open air and a broader view, rather than another church or museum interior.
What to look for
- Walk the tree-lined ramparts of the sixteenth-century fortress.
- Look back toward Siena's centre and outward to the hills.
Useful to know
- Allow around 40 minutes for a circuit and views.
- Check current access before setting out; published hours for the grounds were not confirmed.
