Further development was undertaken after the house became a seminary and then a Roman Catholic grammar school (which later became Prior Park College).
In the 1990s 11.3 hectares (28 acres) of the park and pleasure grounds were acquired by the National Trust and a large scale restoration undertaken.
Features of Prior Park Landscape Garden include a Palladian architecture bridge, lake and ancillary buildings.
[14][15] In November 2002, a large-scale restoration project began on the cascade, serpentine lake and Gothic temple in the wilderness area, this is now complete.
[15] The garden's features include a Palladian architecture bridge (one of only four of this design left in the world),[6][7][8] Gothic temple, gravel cabinet, Mrs Allen's Grotto,[16] the ice house,[17] lodge[18] and three pools with curtain walls[19] as well as a serpentine lake.
[23] The Palladian bridge, which is a copy of the one at Wilton House,[24] has been designated as a Grade I listed building[25] and scheduled monument.
[28] The Palladian Bridge later featured on the cover of the 1996 album Morningrise by Swedish progressive metal band Opeth.
