The town was entirely buried by a sea of mud which preserved it for centuries including even some of the wooden structure. Important excavations led in 1980’ shew to the world the big tragedy. During the walking tour you can visit the most important buildings. Interesting is to notice the differences with Pompeii. Herculaneum is most famous for having been lost, along with Pompeii, Stabiae and Oplontis, in the eruption of Mount Vesuvius beginning on August 24, 79 AD, which buried them in superheated pyroclastic material that has solidified into volcanic tuff. Since the discovery of bones in 1981, some 150 skeletons have been found. Herculaneum was a smaller town with a wealthier population than Pompeii at the time of its destruction. After the eruption of Mount Vesuvius in 79 AD, the town of Herculaneum was buried under approximately 20 meters (50-60 feet) of mud and ash. It lay hidden and nearly intact for more than 1600 years until it was accidentally discovered by some workers digging a well in 1709. From there, the excavation process began but is still incomplete.
