Pontremoli (Latin Apua; Pontrémal in the local dialect) is a small city, comune former Latin Catholic bishopric in the province of Massa and Carrara, Tuscany region, central Italy.
Literally translated, "Pontremoli" derives from "Trembling Bridge" ( ponte - "bridge" and tremare - "to tremble"), with the commune having been named after a prominent bridge across the Magra.
Pontremoli is in the upper valley of the Magra, 40 kilometres (25 mi) northeast of La Spezia by rail and 90 kilometres (56 mi) south-southwest of Parma.
Pontremoli is believed to have been first settled around 1000 BC. It was known in Roman times as Apua. The commune later became an independent municipality in 1226 thanks to Federico II who chartered the free municipality, partly because of its mountainous terrain. This terrain in the valley of the Magra also made Pontremoli a target for numerous conquests from rival Italian and foreign lords. Pontremoli was controlled by various aristocratic families, including the Malaspina (in 1319) and the Antelminelli (in 1322). The conflict between the rival Guelfi and Ghibellini factions in the early fourteenth century resulted in the construction of the Great Bell Tower (Il Campanone) to separate the rival camps. During these Medieval times Pontremoli was often visited by pilgrims travelling from Canterbury to Rome.
