Amalfi (, , ) is a town and comune in the province of Salerno, in the region of Campania, Italy, on the Gulf of Salerno. It lies at the mouth of a deep ravine, at the foot of Monte Cerreto (1,315 metres, 4,314 feet), surrounded by dramatic cliffs and coastal scenery. The town of Amalfi was the capital of the maritime republic known as the Duchy of Amalfi, an important trading power in the Mediterranean between 839 and around 1200. In the 1920s and 1930s, Amalfi was a popular holiday destination for the British upper class and aristocracy. Amalfi is the main town of the coast on which it is located, named Costiera Amalfitana (Amalfi Coast), and is today an important tourist destination together with other towns on the same coast, such as Positano, Ravello and others. Amalfi is included in the UNESCO World Heritage Sites. A patron saint of Amalfi is Saint Andrew, the Apostle, whose relics are kept here at Amalfi Cathedral (Cattedrale di Sant'Andrea/Duomo di Amalfi). History Amalfi held importance as a maritime power, trading grain from its neighbours, salt from Sardinia and slaves from the interior, and even timber, in exchange for the gold dinars minted in Egypt and Syria, in order to buy the Byzantine silks that it resold in the West. Grain-bearing Amalfi traders enjoyed privileged positions in the Islamic ports, Fernand Braudel notes. The Amalfi tables () provided a maritime code that was widely used by the Christian port cities. Merchants of Amalfi were using gold coins to purchase land in the 9th century, while most of Italy worked in a barter economy. During the late 9th century, long-distance trade revived between Amalfi and Gaeta with Byzantine, the latter which benefited from a flourishing trade network with the Arabs. An independent republic from the 7th century until 1073, Amalfi extracted itself from Byzantine vassalage in 839 and first elected a duke in 958; it rivalled Pisa and Genoa in its domestic prosperity and maritime importance before the rise of the Republic of Venice. In spite of some devastating setbacks it had a population of some 70,000 to 80,000 reaching a peak about the turn of the millennium, during the reign of Duke Manso (966–1004). Under his line of dukes, Amalfi remained independent, except for a brief period of Salernitan dependency under Guaimar IV. In 1073, the republic fell to the Norman countship of
