Luján is a city in the Buenos Aires province of Argentina, located 68 kilometres north west of the city of Buenos Aires. The city was founded in 1755 and has a population of 94,000.
Luján is best known for its large neo-gothic Basilica, built in honor of the Virgin of Luján, the patron saint of Argentina. Every year, more than six million people make pilgrimages to the Basilica, many walking there from Buenos Aires.
The city is known as 'La Capital de la Fe' (Capital of the Faith). It is popular day-trip for non-believers too, with abundant grill restaurants (like most places in Argentina) and souvenir shops with kitsch religious memorabilia.
Its towers stand 106m high and it has a copper roof and bronze doors. The huge church towers over the surrounding flat country and houses the tiny 38 cm high statue of the Virgin.
A large and important organ by French builder Cavaille-Coll stands in the gallery in a state of deterioration, although efforts are underway to see to its restoration.
