Basilica San Ponciano is the oldest church in the city of La Plata, founded shortly after the city's establishment in 1882. It serves as the Archdiocesan Sanctuary of La Plata and is dedicated to Pope Pontian.

Its foundation stone was laid as part of the initial urban layout designed by Pedro Benoit.
