Historical Overview: Origins and Early Development

The Illuminated Block traces its roots to the Spanish refoundation of Buenos Aires in 1580. Its name, “Manzana de las Luces” or “Block of Lights,” references both the street lamps that once illuminated the area and the vibrant intellectual environment fostered by its institutions. By the 17th century, the Jesuits had established a strong presence, founding the Jesuit College (1661) and the Church of San Ignacio (completed in 1722), which became the religious and educational heart of the city (hollymelody.com; 4rentargentina.com).

Architectural Highlights

The Illuminated Block is a showcase of colonial, baroque, and neoclassical architecture. Notable structures include:

San Ignacio Church: Built between 1686 and 1722, it is Buenos Aires’ oldest standing church, displaying baroque design and Jesuit craftsmanship (hollymelody.com).
Jesuit College and Cloisters: Characterized by original adobe walls, cloistered courtyards, and arched galleries.
Sala de Representantes: The legislative chamber where crucial 19th-century political events unfolded (4rentargentina.com).
18th-century Tunnels: A network beneath the block, historically used for communication and defense, accessible today via guided tours (Introducing Buenos Aires; WhichMuseum).

Other important buildings include viceregal houses and the old Customs House, adding depth to the block’s historical narrative.
