Storthes Hall Mansion: built in about 1788 as a private house for the Horsefall family, replacing an earlier house built on the site. Taken over as an asylum in 1904, it became known as the Mansion Hospital and operated as a psychiatric institution alongside the main hospital, its last years saw it providing institutional care for people with learning disabilities, finally closing in 1991. It too was sold to the University of Huddersfield in 1994. The building became Grade II Listed in June 1965. It is now again a private residence "The Mansion".
