Well Siena is definitely worth a visit. Actually, we only really saw the Duomo and the Piazza del Campo, but if you can only see two things in Siena, they are probably the sights you want to see. The Duomo is without a doubt the most over the top, overwrought cathedral I have ever seen – but somehow it kind of works. My thighs are still aching from the climb to the top of the parapet to look out over the city and my only regret is that I didn’t get more time shopping. Are you really surprised?
