Herefordshire initially utilised subscription asylum premises within the Hereford General Infirmary site and following the 1845 act entered into agreement with the Welsh counties of Monmouthshire, Radnorshire and Breconshire to construct the Joint counties premises at Abergavenny.
The new establishment in Burghill, which replaced the original Asylum in Hereford, covered 10 acres and cost £87,873.00
