Monte dei Paschi di Siena

This branch of Monte dei Paschi di Siena — the world's oldest bank, founded in 1472 — sits right on Piazza del Monte 4 in the heart of Grosseto. You can handle cash withdrawals, cardless ATM transactions, and even choose your own banknote denominations at the self-service terminals. It's a small but functional stop if you need euros sorted before heading anywhere else in the Maremma.
