Santísimo Sacramento Church, Tandil, Catholic parish church in Tandil, Argentina.

Santísimo Sacramento Church is the parish church of Tandil, standing at the corner of Belgrano and Fuerte Independencia streets. Its construction began in May 1855 on a lot facing the plaza, near the remains of the fort, and halted in November of that year for lack of workers. The building was planned with double walls, pine roof beams and boards, dung-whitened plaster and a brick floor.

Construction began in May 1855 on a plot at Independencia and Pinto streets, facing the plaza and the fort ruins, after a protemplo commission created in 1853 raised funds through collections, a cattle auction and a levy on chacra concessions. Work halted in November that year for lack of labourers, during a year the town suffered four indigenous incursions. The 1854 plans were approved by decree on 20 June 1854.

The church serves as a spiritual center for Tandil's Catholic community and hosts masses, celebrations, and religious gatherings that shape the city's devotional life.

The church is generally accessible for visitors to explore its interior and exterior spaces. Check for service times as these affect when you can visit comfortably.

The first chapel on the site was built of raw brick, 12 varas long by 7 wide, with wooden doors and windows and a straw roof; other buildings of the fort were of rough stone with clay-and-straw joints. A law of the time required every new fort to have a chapel and a chaplain.
