This painting shows the Bethleham Royal Hospital, London. The first asylum for the insane in England. The word bedlam is derived from the name of the hospital and became a generic term for all asylums and colloquially to mean random disorder or chaos.
Bedlam was infamous for its ill treatment of the inmates, and this picture shows visitors, a man being shackled by the attendants (early nurses?) and the overcrowding and squalor of the hospital during the mid 1700s
