Hospital endowed by Thomas Walker on his estate Yaralla for convalescents who were sent from other hospitals to the greenery and fresh air of the hospital on the river at Concord. Designed by John Sulman and opened in 1893. The complex, including the Joanna Walker Memorial Childrens’ Convalescent Hospital that was also in the grounds, was transferred to the New South Wales Health Department in 1979. It is now occupied by the Rivendell School and the Rivendell Child, Adolescent and Family Mental Health Service.
