About Colonial Buenos Aires: from the Manzana de las Luces to El Zanjón

Begin at the Manzana de las Luces, at Perú 272, with the Iglesia de San Ignacio, the oldest church still standing in the city. Walk south down the Calle Defensa into San Telmo for a booked tour of El Zanjón, at Defensa 755, where tunnels and cisterns lie beneath a 19th-century house, and finish in Parque Lezama, where some historians place the city’s first founding in 1536. On Sundays the Feria de San Telmo fills Defensa on the way.
