Located in the shadow of Mount Vesuvius, Herculaneum was an ancient Roman town destroyed by volcanic pyroclastic flows in 79 AD. Its ruins are located in the comune of Ercolano near Naples.
As a UNESCO World Heritage Site, it is famous as one of the few ancient cities that can now be seen in much of its original splendour, as well as for having been lost, along with Pompeii, Stabiae, Oplontis and Boscoreale, in the eruption of Mount Vesuvius in AD 79 that buried it. Unlike Pompeii, the deep pyroclastic material which covered it preserved wooden and other organic-based objects such as roofs, beds, doors, food and even some 300 skeletons which were discovered in recent years along the seashore. It had been thought until then that the town had been evacuated by the inhabitants.
Herculaneum was a wealthier town than Pompeii, possessing an extraordinary density of fine houses with, for example, far more lavish use of coloured marble cladding.
Ancient tradition connected Herculaneum with the name of the Greek hero Heracles, an indication that the city was of Greek origin. In fact, it seems that some forefathers of the Samnite tribes of the Italian mainland founded the first civilization on the site of Herculaneum at the end of the 6th century BC. Soon after, the town came under Greek control and was used as a trading post because of its proximity to the Gulf of Naples. In the 4th century BC, Herculaneum again came under the domination of the Samnites. The city remained under Samnite control until it became a Roman municipium in 89 BC.
The buildings at the site are grouped in blocks (insulae), defined by the intersection of the east-west and north-south streets.
The most famous of the luxurious villas at Herculaneum is the Villa of the Papyri. It was once identified as the magnificent seafront retreat for Lucius Calpurnius Piso Caesoninus, Julius Caesar's father-in-law.The villa stretches down towards the sea in four terraces. Piso, a literate man who patronized poets and philosophers, built a fine library there, the only one to survive intact from antiquity.
The Central Thermae were bath houses built around the first century AD. Bath houses were very common at that time, especially in Pompeii and Herculaneum. Per common practice, there were two different bath areas, one for men and the other for women. These houses were extremely popular, attracting many visitors daily. This cultural hub was also home to several works of art, which can be found in various areas of the Central Thermae site.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
