Imperia is a coastal city and comune in the region of Liguria, Italy. It is the capital of the Province of Imperia, and historically it was capital of the Intemelia district of Liguria. Mussolini created the city of Imperia on 21 October 1923 by combining Porto Maurizio and Oneglia and the surrounding village communes of Piani, Caramagna Ligure, Castelvecchio di Santa Maria Maggiore, Borgo Sant'Agata, Costa d'Oneglia, Poggi, Torrazza, Moltedo and Montegrazie. Imperia is well known for the cultivation of flowers and olives, and is a popular summer destination for visitors. The local Piscina Felice Cascione indoor pool has hosted numerous national and international aquatics events. Imperia consists of the two historical districts of Porto Maurizio and Oneglia, which lie on either side of the River Impero that gives its name to the city. Porto Maurizio is situated on a peninsula to the west of the river, stretching along the coastline. It is the more colourful and wealthy district of the city, threaded by narrow lanes known as carrugi, and its economy centres around the tourist industry. It was a possession of Genoa from the 13th century. Oneglia (Inéja in Ligurian) lies on an alluvial plain to the east of the Impero, and with its working port is the more modern and industrial of the two districts. At its centre lies Dante Square, from which radiate some of the principal roads of the city.
