Largely preserved under the ash, the excavated city offers a unique snapshot of Roman life, frozen at the moment it was buried and providing an extraordinarily detailed insight into the everyday life of its inhabitants. Organic remains, including wooden objects and human bodies, were entombed in the ash and decayed away, making natural molds; and excavators used these to make plaster casts, unique and often gruesome figures from the last minutes of the catastrophe. The numerous graffiti carved on the walls and inside rooms provides a wealth of examples of the largely lost Vulgar Latin spoken colloquially, contrasting with the formal language of the classical writers. Pompeii is a UNESCO World Heritage Site status and is one of the most popular tourist attractions in Italy, with millions of visitors every year.
