Azul

Its principal, goods-producing economic activities are agriculture and the raising of cattle for meat and leather exports. Home to a dynamic services sector, over 2,000 commercial businesses are registered in the city.

The town was founded on December 16, 1832, following Governor Juan Manuel de Rosas' orders for the construction of a fort, San Serapio Mártir del Arroyo Azul, to guard against indigenous raids. Subsequent land grants led to the development of a stable community, and in 1895, Azul was formally declared a town by provincial authorities. The local cathedral, Nuestra Señora del Rosario, was consecrated in 1906.

The town's cemetery portal and main slaughterhouse were both designed by architect Francisco Salamone, and contain elements of Art Deco style. Built in the late 1930s, these buildings were some of the first examples of modern architecture in rural Argentina. The town was the scene of an attack on outlying Army barracks by far-left ERP militants on January 19, 1974, the most violent assault of its kind in the country up to that point.

Azul is home to the schools of Agronomy and Law of the National University of Central Buenos Aires.
