1960, Frosinone saw a continuation of the trends it had seen in the immediate postwar period: a steady decline in the agricultural sector (to 9% of employed residents), a modest increase in industry (to 36%) and a significant rise in tertiary activities, in which 54% of the workforce is engaged. The reconstruction work continues, including: renovations to important buildings (such as the sites of the Prefecture, the Bank of Italy, the halls of Justice, the Chamber of Commerce and the Post and Telecommunications); new construction (such as the Civil Hospital, public housing and the Edera skyscraper); the expansion of the urban and extra-urban road network; and providing public water connections to nearby rural settlements. It was within this general framework that the industrialization process began. In 1962, the Industrialization Unit of the Sacco Valley was established and the Rome-Naples motorway section was constructed. The motorway artery, which crosses the entire valley longitudinally, was hugely important in ending the isolation of the capital and of the entire province. Previously the region had only the ancient Via Casilina and less functional roadways for inter-regional connections, and the Rome-Naples railway had not yet been electrified. The following decades saw economic development, but also periods of crisis. This led, especially in the lower Frosinone, to the development of an industrial and commercial center that was predominantly modern, but suffered from a disordered and irrational approach to urban development, caused by a failure to implement the zoning plan and a tendency to engage in building speculation — this tendency has been increasing since the 1960s and continues today, even though the population stopped growing many years ago. Geography Frosinone is in Latium and is the main city of the Valle Latina ("Latin Valley"). The town is surrounded by the Ernici and Lepini mountain ranges. Climate Cityscape Religious architectures Cathedral of Santa Maria Assunta The Cathedral of Santa Maria Assunta is the most important church in Frosinone and is located on the highest point of the hill on which the historic center of the city stands (Upper Frosinone). It was extensively remodeled in the 18th century, referring to Sant'Andrea della Valle in Rome. It features a bell tower (Il Campanile), 68 meters high, which is considered the most emblematic monument of the city, with three rows of mullioned windows. The facade of the cathedral is in white marble. Among the works of art preserved in the
