[1] The site was previously occupied by Llanfrechfa Grange, a country house which was built for Charles Prothero in the middle of the 19th century.

[3] It passed to Francis Johnstone Mitchell in 1860,[4] the Cleeve family in 1913, Sir John Cecil Davies in 1921, Elsie Louise Llewelyn in 1922 and to a property developer in 1933.

[2] In 1953, Llanfrechfa Grange started providing long term residential accommodation for people with learning disabilities.

[5] Although it still had more than 300 residents in 1983,[5] following the introduction of Care in the Community shortly thereafter, the hospital went into a period of decline and it finally closed to inpatients in 2008.

[6] In 2017 work to create and construct Grange University Hospital, a new specialist critical care centre, started on the site.
