The Mount Hospital.

The Mount Hospital in Bishopstoke, Hampshire was a popular smaller hospital which mostly focused on rehabilitation for elderly patients but had various other outpatients’ departments.
The Mount started as small private estate with the first house built by a wealthy farmer in 1844. It was later bought by a Captain Hargreaves in the 1870s. When he died it was bought by a Mr Cotton who rebuilt it in 1893. His imposing Victorian mansion replete with impressive tower forms the heart of the site. It originally had impressive gardens too suitable for a house of its standing with an arboretum, formal gardens and a Victorian water garden. In 1927 it was sold to Hampshire County Council who converted it into a hospital reusing the original Victorian house, as well as building a range of other buildings including another impressive art deco-ish ward building.
The Hospital closed a few years back in a clamour of local annoyance following years of campaigning to keep it open.
