Sean Ross Abbey, Convent and former mother and baby home in County Tipperary, Ireland

The site features a Georgian mansion with two stories above a basement level, surrounded by gardens and outbuildings. Historical structures including a lime kiln and foundations of medieval religious buildings remain on the expansive grounds, which now primarily house St Anne's Special School.

St Crónán is believed to have founded a monastery at Sean Ross in the 6th century, but abandoned the wooded morass for Roscrea. Augustinian canons relocated to Sean Ross in 1485. Corville House, built around 1750, was home to the Prittie family (Barons Dunalley) and later Count John O'Byrne until 1930. The Sisters of the Sacred Hearts of Jesus and Mary arrived in 1932 and ran a mother and baby home until 1970.

The home's name survives in the Angels Plot, an unmarked burial area within the grounds for an unknown number of mothers and babies. The most common exit for a child was return to mother or family, at 44 percent, while 487 babies were adopted in the United States. The 1952 birth of Anthony Lee to Philomena Lee here underlies Martin Sixsmith's book and the film Philomena.

The campus is south of Roscrea in County Tipperary, with St Anne's Special School, opened in February 1971, still operating on part of it. In February 2018 the sisters offered much of the campus for sale, excluding the school and the cemeteries, which the congregation keeps and leaves accessible. The entrance is marked by stone pillars, one carrying a plaque reading "Sacred Heart of Jesus have mercy on us" and "Sean Ross Abbey".

Journalist Alison O'Reilly uncovered the names of 1,024 children who died at Sean Ross Abbey, published in the Irish Daily Star on 27 July 2020 after records were obtained under the Freedom of Information Act. The official list records 128 deaths from marasmus, severe malnutrition, alongside convulsions, exhaustion and two from sun and heat stroke. One certificate gives acute heart failure from choking on porridge.
