Llanidan Hall is situated in the south corner of Anglesey on the shore of the Menai Strait (nprn 15733). It lies within parkland (700033) and its pleasure grounds run south-west to north-east between the south front of the house and the park. They are bounded on the south-west by the walled former kitchen garden (15735) and on the south-east by ha-ha which curves around at the ends (15734). In the early seventeenth century, garden enclosures were reputedly made to the south of the house. In the period 1783-1816 almost half of the southern end of the walled garden was removed, creating the present fan-shaped garden. This garden was informal, mostly lawn. In 1900 it was mainly lawn with specimen trees, paths and a shrubbery which, by the 1980s, had become completely overgrown. Subsequent restoration and redesign led to the thinning of the shrubbery, the restoration of a small pool with fountain and waterfall added, and creations which included a pergola, an oblong garden enclosed by a camellia hedge, and a magnolia avenue. A knot garden was made immediately west of the house. The likely oldest plants in the garden, a row of beeches along the outside of the south-east wall of the kitchen garden, now flank a grass walk planted with daffodils, known as the Daffodil Avenue.

In the western part of the grounds, just beyond the walled garden, is Ffynnon Nidan, traditionally a holy well (32166), which feeds a pond or pool.

1. Parklands & Gardens of Wales No:PGW.GD46 Grounds incorporate St Nidans Church.
LLANIDAN is an ancient site incorporating a circular churchyard with yew trees and a holy well. Early seventeenth-century features remaining include the walls of a walled garden and traces of a formal park. Llanidan has a small but well preserved late eighteenth-century landscape park in an exceptional position on the Menai Strait, with well framed views to Snowdon. Its sophistication, with a sea shore bank and very fine ha-ha, suggests that a professional landscaper may have advised on the layout. -52; 1772-1802; 1802-82; c. 1937; 1984 onwards.
