[1] The hospital's origins lie in a bequest by Dr Paul Parnell to establish an asylum in Lincoln.

[3] It was at the asylum that, in the 1830s, Robert Gardiner Hill, with the support of Edward Parker Charlesworth, pioneered a mode of treatment that suited "all types" of patients, so that mechanical restraints and coercion could be dispensed with—a situation he finally achieved in 1838.

[8] The hospital joined the National Health Service in 1948 and, following the introduction of Care in the Community, closed in 1985.

[9] City of Lincoln Council acquired the hospital and operated it as an events venue until August 2016 when it sold it to R. W. Stokes & Sons who have redeveloped the property as a new business headquarters, cafe, restaurant and theatre.

[10] A tropical glasshouse, the Sir Joseph Banks Conservatory, was moved from the site in late 2016.
