Stannington Sanatorium was the first purpose built hospital for tuberculous children in the United Kingdom. Opening in 1907 it was funded through the Poor Children's Holiday Association (now Children North East) prior to the introduction of the National Health Service in 1947. Although initially set up to treat children suffering with tuberculosis the hospital became a general children's hospital in 1953 when tuberculosis went into decline following the introduction of antibiotic treatments and eventually closed in 1984. Upon closure the records from the Sanatorium were deposited with Northumberland Archives and from August 2014 to July 2015 the 'Stannington Sanatorium Project' ran, funded by the Wellcome Trust, to catalogue and part-digitise these records. We would now like to share what we have learnt about how tuberculosis affected children in the mid-20th century and about the history of Stannington Sanatorium, a fascinating institution, with you. We hope you enjoy your tours around Stannington!
