A city is a relatively large and permanent settlement. Although there is no agreement on how a city is distinguished from a town within general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.
For example, in the American state of Massachusetts an article of incorporation approved by the local state legislature distinguishes a city government from a town. In the United Kingdom and parts of the Commonwealth of Nations, a city is usually a settlement with a royal charter. The belief in this distinction is also common in England, where the presence of a cathedral is thought by many to distinguish a 'city' (sometimes called a 'cathedral city') from a 'town' (which has a parish church]citation needed[); the belief is incorrect (Chelmsford, for example, became a city only in 2012, but had a cathedral for most of the 20th century).
The Campanian volcanic arc is a volcanic arc that consists of a number of active, dormant, and extinct volcanoes in the Campania region of Italy. The Campanian volcanic arc centers on the bay of Naples and includes:
"Campanian volcanic arc" is somewhat a term of convenience, since the area is part of the same large area of intense volcanic and seismic activity that includes, further to the south, the active island volcanoes of Stromboli, and Vulcano off the north coast of Sicily and even the largest active volcano in Europe, Mt. Etna, on Sicily itself.

Mount Vesuvius (Italian: Monte Vesuvio, Latin: Mons Vesuvius) is a stratovolcano in the Gulf of Naples, Italy, about 9 kilometres (5.6 mi) east of Naples and a short distance from the shore. It is one of several volcanoes which form the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier and originally much higher structure.
The ancient Roman city of Pompeii has been frequently featured in literature and popular culture since its modern rediscovery.
