Avellino (avelˈliːno) is a town and comune, capital of the province of Avellino in the Campania region of southern Italy. It is situated in a plain surrounded by mountains east of Naples and is an important hub on the road from Salerno to Benevento. Before the Roman conquest, the ancient Abellinum was a centre of the Samnite Hirpini, located on the Civita hill some outside the current town, in what is now Atripalda. The city could correspond to the ancient Velecha, documented by coins found in the area. Abellinum was conquered by the Romans in 293 BC, changing name several times in the following centuries (Veneria, Livia, Augusta, Alexandriana, and Abellinatium). However, the construction of a true Roman town occurred only after the conquest by Lucius Cornelius Sulla in the civil wars in 89 BC. He razed the old site and in 82 BC founded the colony Veneria Abellinatium on the left bank of the river Sabato. The new city was surrounded by massive walls and had an orthogonal hippodamian urban layout. In 7 AD Augustus changed its name to Livia Augusta in honour of his wife, Livia Drusilla who owned the territories between Abellinum and Aeclanum. In the 3rd century Alexander Severus expanded the colony under the title of Livia Augusta Alexandrina with a massive immigration of oriental settlers. This helped to spread ancient Levantine cults such as Sol Invictus in the territory. There followed economic crises (III and IV centuries), violent earthquakes (346) and disastrous volcanic eruptions (472). The town was Christianised around 500, becoming an episcopal seat. There were invasions of the Goths (535 - 555) and the Vandals. After the Lombard conquest of southern Italy, the ancient city was abandoned in 568 (it is disputed if completely or partly) and a new settlement grew on the Terra hill, corresponding to the modern Avellino. Defended by a castle, it became part of the Duchy (later Principality) of Benevento and, after the latter's fall, of the Principality of Salerno. In 1100, during the Norman rule of southern Italy, it was acquired by Riccardo dell'Aquila.
