Brief description of site

Trewithen is a 20th-century woodland garden of around 6 hectares within a larger park, woodland and agricultural estate.

Brief history of site

Trewithen, in the late-17th century the property of Courtenay Williams, was purchased in 1715 by Philip Hawkins of Pennans. Philip Hawkins made improvements to the existing house in 1723. A plan of 1747 shows the extensive landscape developed by Thomas Hawkins before his death in 1766. His son, Sir Christopher Hawkins, extended the property and in 1824 commissioned a plan from Henry St Aubyn to extend the park to the north, east, and west of the house, producing a picturesque circuit ride.
