Brief description of site

Tewin Water has the remains of a late-18th-century landscape park covering about 77 hectares. The park has been affected by 20th-century institutional development.

Brief history of site

An estate map of around 1785-9 shows the layout of land around the house at that time, including a 16 hectare paddock called The Warren, which Lady Cathcart labelled the park, together with a 3 hectare garden lying adjacent. In 1797 Tewin Water house was demolished and rebuilt in Neoclassical style. In 1799 the fifth Earl engaged Humphry Repton to improve his estates. In 1902 Alfred Beit acquired the estate, extending the house and adding formal elements to the gardens. During the late-1940s and 1950s the estate was sold into divided ownership.
