SAN LORENZO

city and port accessible to oceangoing vessels, southeastern Santa Fe province, northeastern Argentina, on the Ro Paran. The settlement grew up around a monastery, which the Argentine liberator Jos de San Martn used as headquarters during the 1813 Battle of San Lorenzo. It was given city status in 1944. The city's economic base is varied, with petrochemical works that are among the largest in Argentina. It is a trade and manufacturing centre for the agricultural hinterland, in which corn (maize), flax, wheat, sugarcane, and sunflowers are cultivated. The numerous manufacturers produce gasoline, foodstuffs, glass, paper, ceramics, construction materials, and other goods. San Lorenzo, located 14 mi (23 km) north of the city of Rosario, is an integral part of Greater Rosario. Pop. (1980) 78,983. Pacific port city, Valle department, southern Honduras, situated on the northern shore of the Gulf of Fonseca. The shallow waters of the gulf long precluded development of the port, but construction of major roads nearby and the inconvenience of the old port at Amapala fostered the project. Construction began in 1977; a deep channel was dredged to enable oceangoing vessels to berth beside port facilities. Cargo-handling capacity was designed for 1.1 million tons per year upon completion. Industries in the city include a sawmill that processes pitch pine for export, a barbed-wire plant for domestic ranch fencing, a textile mill, a vegetable oil processing plant, and a dairy. Fishing in the Gulf of Fonseca was threatened in the late 1970s by pollution of the Choluteca River, which flows into the gulf. San Lorenzo is served by the Inter-Ocean Highway, which links it to the Inter-American Highway, Tegucigalpa and the interior, and the Caribbean coast. An airport at Amapala on Tigre Island also serves San Lorenzo. Pop. (1975 est.) 9,261. early Renaissance-style church designed by Brunelleschi and constructed in Florence from 1421 to the 1460s, except for the facade, which was left uncompleted. Also by Brunelleschi is the Old Sacristy (finished in 1428). The New Sacristy, more commonly called the Medici Chapel, is largely the work of Michelangelo, as are the celebrated Medici Tombs it houses. Michelangelo also designed the Laurentian Library, which is located off the cloister. The tombs of the grand dukes of Tuscany line the walls of the Baroque Chapel of the Princes, which was begun in 1604 according to plans of Ferdinand I de' Medici.
