Gwysaney Hall (nprn 35855) is located on the edge of a plateau to the north of Mold. It is notable for the historical interest of its park which has origins as a seventeenth-century deerpark with some contemporary walling and trees; also for its fine nineteenth-century arboretum containing many unusual mature specimens, and for the Victorian/Edwardian layout of its garden (86578). 

The park, first mentioned in 1664, is roughly rectangular, aligned north by south, on rolling ground sloping up from south to north. It is bounded on the south by the Mold-Rhydymwyn road (A541), on the north and north-east by woodland, and elsewhere by farmland. It is rectangular, aligned north by south, but was formerly more extensive on the east, west and north; about two thirds of the historic park is now farmland. The remainder is pasture with isolated mature trees, mainly oak, but with some lime and very ancient sweet chestnut. The drive, formerly flanked by sweet chestnuts, approaches from the main entrance and lodge on the A541 to the higher, more level ground to the south of the house. Just east of the drive, in the middle of the park, is an evergreen oak.
A map of 1757 shows the deer park as considerably smaller than the later park. It was bounded by paling on its eastern side and walling on its western. The wall bounding the western edge of the arboretum is part of this park wall, and probably dates to c.1664. The park is shown as dotted with trees, with an area of woodland in the eastern section. To the south of the house is a wide avenue; the sweet chestnuts that remain are probably remnants of this avenue.

Gardens lie around the house (86578).
