The Stanway Watergarden, one of the finest in England, was created in the 1720s for John Tracy, probably by Charles Bridgeman, gardener to Lord Cobham at Stowe, Buckinghamshire from 1719 and Royal Gardener from 1727, who invented the English style of gardening, which superceded the Franco-Dutch style.

Typically Bridgemanic is the Canal, a magnificent formal sheet of water, situated unusually on a terrace 25 feet above the house, and the Cascade (the largest in Britain, partially restored), fed by water flowing under the Pyramid from the Pyramid Pond.

The Tithe Barn Pond adds to the watery feel of the garden, which also includes fine specimen trees, broad terraced lawns and herbaceous borders.
