The San Isidro Cathedral is located in the city of San Isidro, in the province of Buenos Aires, Argentina. It is at 16200th Del Libertador Avenue, opposite Plaza Mitre or Plaza de San Isidro in San Isidro's historic quarter.
Built on the site of a 1706 chapel opened by the city's founder, Captain Domingo de Acassuso, the cathedral was designed by French architects Dunant and Paquin, and inaugurated on July 14, 1898.
Constructed in neogothic style, it stands 68 m (223 ft) tall. Its base is a Latin cross. Its walls are built from stone and bricks, and it has stained glass windows. The cathedral underwent a restoration project which was completed in 2007.
Isidore the Labourer festival is celebrated on 15 May each year.
Nearly 100 metres in front of the cathedral is the Plaza de San Isidro, and on it, is the San Isidro artisan fair since 1971. This fair has 100 stands, where people can buy leather, wood, textile, metal and ceramic products.
The "San Isidro Artisan Fair" is oldest in the Buenos Aires Province.
