How Nearly 800 Babies Ended Up in a Septic Tank at a Catholic Home for Unwed Mothers

Irish authorities have begun a long-awaited excavation at a site in Tuam, County Galway, where the remains of nearly 800 babies are feared to have been buried in a septic tank on the grounds of a Catholic-run institution for unwed mothers.

The site, once home to the Bon Secours Mother and Baby Home, was operated by Catholic nuns between 1925 and 1961. The facility housed pregnant women—many of whom were rape or incest survivors—who were forced to give up their children after birth. For decades, what happened to many of those children remained shrouded in silence, until a local historian, Catherine Corless, uncovered death certificates for 798 children but found burial records for only one.

Her revelations in 2014 shocked the world and forced the Irish government to launch a national inquiry into institutional abuse. Corless’s findings indicated that the bodies of the infants—some as young as 35 weeks gestation—may have been discarded in what was once a sewage tank, euphemistically referred to as “the pit.” That site is now bordered by a modern apartment complex and a remembrance garden.

“This is not just a mass grave—it’s a symbol of how society turned its back on vulnerable women and children,” Corless said in an interview with Sky News. “These children deserve dignity in death, even if they were denied it in life.”

Excavations began earlier this week and are expected to last up to two years as forensic teams work to identify remains and prepare them for proper reburial. The project represents a significant step in acknowledging the trauma of survivors and the dignity of the deceased.

Annette McKay, whose sister is believed to be among the 796 infants, recounted the chilling words her mother, Margaret “Maggie” O’Connor, was told after losing her baby at the home: “She was pegging washing out and a nun came up behind her and said, ‘The child of your sin is dead.’”

The Bon Secours facility was part of a wider network of state-sanctioned homes and so-called Magdalene Laundries, institutions where women deemed “fallen”—often just victims of rape, orphans, or unmarried mothers—were confined, exploited for labour, and subjected to cruel conditions. The last of such laundries only shut down in the 1990s.

A 2021 state inquiry found that nearly 9,000 children died in 18 mother-and-baby homes across Ireland, mostly from preventable diseases like respiratory infections and gastroenteritis. In 2014, the Irish government issued an official apology, and by 2022, it had disbursed over $32 million in compensation to more than 800 survivors.

Now, the excavation in Tuam not only seeks to provide closure to grieving families but also stands as a stark reminder of how institutional cruelty, silence, and societal judgment can bury both lives and truths for generations.
