Smyllum Park Orphanage was opened in 1864 at Smyllum Park in Lanark, Lanarkshire, Scotland.
The institution was run by a Catholic order of nuns and housed 11,600 children aged between one and 14 years old, including those who were blind or deaf-mute, before it closed in 1981.
Decades later an unmarked mass grave was found at nearby St Mary's Church in Lanark which is just a three-minute drive away from the care home.
The orphanage is now being examined by the Scottish Child Abuse Inquiry into historical allegations of the abuse of children in care.
