Alabaster
Volterra is famous for its alabaster. The white chalky alabaster mined around here is classed as some of the best in the world.
In Volterra you can still see the alabaster artisans carving this white stone as they have for more than two thousand years. They make all sorts of things out of it, ranging from animals to picture frames to sculptured busts to candle stick holders.
If you are a fan of alabaster then you are in luck - Volterra has plenty of shops selling it carved into almost anything your heart desires.
You can also visit the Ecomuseo Dell'Alabastro (the Alabaster Museum), where you can check out a re-creation of an ancient artisan's workshop, and see some unusual alabaster creations such as musical instruments and a fried egg.
