The Grim's Dyke Hotel at the western end of the walk is a nice place to stop for refreshments. You could enjoy a delicious Afternoon Cream Tea before a stroll around the beautiful Lady Gilbert's Gardens. There's 40 acres to explore with a vegetable garden and peaceful woodland.
Sir William Schwenck Gilbert bought the property in 1890. During his 21 years there, he made a number of changes to the house and grounds. He planted trees and rhododendrons, developed the farm which was part of the estate, and built a number of greenhouses beyond the moat and over the dyke. There was a kitchen garden, orchard and vinery and, for Lady Gilbert who was a keen gardener, a sunken rose garden was constructed on the terrace above the moat.

Dog Walking

The woodland and parkland trails are ideal for dog walking so you'll probably see other owners on your visit.

Bentley Priory was occupied by the RAF from 1926 until the spring of 2008, perhaps the most important time in its history was during World War Two when it was the headquarters of Fighter Command. The site has been sold to a developer and plans to convert some of the building to luxury apartments and build new houses have been approved. The Bentley Priory Battle of Britain Trust has secured part of the building to be used as a museum and memorial dedicated to those who served in the RAF. In September 2008 the site was open to the public for the first time part of the Civic Trust Heritage Open Days, this photograph shows the south face of the main buildings on one of those days.

Grim's Dyke Hotel, from the garden. - - 311183

Grim's Dyke Hotel, from the garden. This area is on Harrow and Weald Comon at the western end of the route. Grim's Dyke is most famous for its association with the librettist, Sir William Schwenck Gilbert, the writing half of the Gilbert & Sullivan partnership, who lived in the house from 1890 to his death in 1911. The name Grim's Dyke comes from an ancient defensive earthwork which runs from Pinner Hill to Bentley Priory. The House was built there in 1870 for the Victorian Painter Frederick Goodall, who had bought 100 acres of land at Harrow Weald in 1856 but was unable to build for 12 years until the expiry of a lease. During that time he landscaped the area and planted trees, setting aside 30 acres parallel to the ancient earthwork for the house and gardens. Work started on the house in 1870 and was completed in 1872.

Gilbert's Lake. Gilbert's greatest joy was the large lake he had excavated to the south of the house. It had an island in the middle and a changing hut and boathouse on the shore. Every day in the summer he would bathe there - a habit which eventually cost him his life. On 29th May 1911 Gilbert invited two local girls to swim in the lake. He died attempting to help one of them when she got into difficulties.
