The Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales was established in 2002 and given statutory status in 2022. It is administered by Cadw, the historic environment agency of the Welsh Government.[3][4]Elisabeth Whittle described Cadw as having a "somewhat special and guiding role" in the preservation of historic parks and gardens, since they are "an integral part of Welsh archaeological and architectural heritage".[5] The register includes just under 400 sites, ranging from gardens of private houses, to cemeteries and public parks. Parks and gardens are listed at one of three grades, matching the grading system used for listed buildings. Grade I is the highest grade, for sites of exceptional interest; Grade II*, the next highest, denotes parks and gardens of great quality; while Grade II denotes sites of special interest.[6]
There are five registered parks and gardens in Rhondda Cynon Taf. Two are listed at Grade II*, and three at Grade II. Two were constructed as public parks and the others are parks and gardens that were originally built around country houses.

Park, country house garden and kitchen garden[9][10][11] The mid-eighteenth-century landscape park and parts of the garden were probably laid out when the present house was built, the terraced garden is nineteenth century. Listed buildings within the grounds include the house (Grade II*), the stables and the old laundry building (both Grade II).[12][13]

The manor house is listed (Grade II) as are several other structures including the terraces and statues of heraldic animals.[17][18]
Park, country house garden and kitchen garden[19][20][21] The layout is mainly the work of George Thomas Clark in the late nineteenth century and includes terraced gardens, a woodland garden and park with a lake and ornamental pond. There are several listed structures within the area including the house (Grade II*), stone benches in the sunken garden, and the terrace walls.[22][23]
