This stunning abbey, halfway between Grosseto and Siena, is in Gothic style and it was the first gothic style abbey to be built in Tuscany.
Its peculiar, as you can easily see, is that the ceiling is missing. It was built between 1218 and 1288 by the Cistercian monks.
It took almost a century to be finished!
But how comes the ceiling is missing? In 1786 a lightning struck the bell tower which collapsed onto the roof. The abbey is now deconsacrated.
Entrance ticket costs 3,50€ per person and it allows you to visit the abbey, the museum and the Eremo di Montesiepi (5 minutesby foot) where you can admire the famous sword in the stone left by Galgano Guidotti.
