 The contents of the tombs were excavated, often chaotically and illegally; over the last few centuries, they have yielded rich and exquisite objects, including ceramics and jewellery which today grace many of the world's museums.One famous and important work of art is the Sarcophagus of the Spouses.The most famous attraction of Cerveteri is the Necropoli della Banditaccia, which has been declared by UNESCO as a World Heritage Site together with the necropolis in Tarquinia.
