About

This 1930s restyled interior is famous for its Rex Whistler association and contains his exquisite romantic mural and the largest exhibition of his works.

There's a fine spring garden and Australasian arboretum, with an understorey of shrubs and wild flowers, an italianate-style summer terrace, and massed hydrangeas which give autumn colour.

A woodland walk gives access to a delightful spring and early summer rhododendron garden.

From the house and grounds, the views across the Menai Strait to the mountains of Snowdonia are simply stunning.
