Augusta (Sicilian: Austa, Greek and Latin: Megara Hyblaea, Medieval: Augusta and Agosta) is a town and comune in the province of Syracuse, located on the eastern coast of Sicily (Italy). The city is one of the main harbours in Italy, especially for oil refineries (Exxon Mobil) which are in its vicinity.

The city is situated in Syracuse and faces the Ionian Sea. The old town is an island, made by cutting an isthmus in the 16th century and is connected to the mainland by two bridges. One bridge was built recently (Viaduct Frederick II of Swabia) and the other built when the city was founded and is called the Spanish Gate. Augusta is home to two ports.

The town was founded by Emperor Frederick II. After the Angevine domination, it became part of Aragonese Sicily and, from 1362, it was a fief of Guglielmo Raimondo II Moncada. It returned a Royal possession (under Spain) in 1560, and was extensively fortified to counter Turkish pirates.

In 1675 its harbour was the seat of naval battle between Spanish and English fleets. The town suffered a major earthquake and tsunami in 1693. During World War II, Augusta was invaded on July 13, 1943 by the Eighth Army of the Allied troops led by British General Montgomery.

Sicily (Italian and Sicilian: Sicilia, [siˈtʃiːlja]; [sɪˈɕilja]) is the largest island in the Mediterranean Sea; along with surrounding minor islands, it constitutes an autonomous region of Italy, the Regione Autonoma Siciliana (Sicilian Autonomous Region).

Sicily is located in the central Mediterranean. It extends from the tip of the Apennine peninsula from which it is separated only by the narrow Strait of Messina, towards the North African coast. Its most prominent landmark is Mount Etna, which is at 3,320 m (10,890 ft) the tallest active volcano in Europe and one of the most active in the world. The island has a typical Mediterranean climate.

The earliest archeological evidence of human dwelling on the island dates from 8000 BC. At around 750 BC, Sicily became a Greek colony and for the next 600 years it was the site of the Greek-Punic and Roman-Punic wars, which ended with the Roman destruction of Carthage. After the fall of the Roman Empire in the 5th century AD, Sicily often changed hands, and during the early Middle Ages it was ruled in turn by the Vandals, Ostrogoths, Byzantines, Arabs and Normans. Later on, the Kingdom of Sicily lasted between 1130 and 1816, subordinated to the crowns of Aragon, Spain, the Holy Roman Empire, and finally the Bourbons, as the Kingdom of the Two Sicilies. It was united with the rest of Italy in 1860, but a subsequent economic collapse led to a wave of emigration, separatism, and the emergence of the Mafia, whose criminal activities pose problems to this day. After the birth of the Italian Republic in 1946, Sicily was given special status as an autonomous region.
