FONTHILL
(From The Successive Houses of Fonthill, Lt.-Col. H.F. Chettle. W.A.M. no. CLXXVI.)
In 1631 the estates were forfeited. Fonthill Gifford was bought by Sir Francis Cottington, Ambassador and Statesman. It is not known whether the house he rebuilt was Sir John Mervyn’s Fonthill I., or another. The Arch and lodge at Fonthill Bishop and the gate opposite the Beckford Arms were built for him and the stream was embanked to form the lake.
Fonthill II. remained in the hands of the Cottington family for 80 years. It was then purchased by William Beckford I. (c.1709) – a descendant of the Mervyns, and the son of a wealthy planter in Jamaica. He became M.P. for the City of London (1743-1776) and Lord Mayor (1762-1770). He died in 1770. Fonthill II. was so improved by Alderman Beckford as to become a new mansion (Fonthill III.).
In 1755 the greater part of Fonthill III. was burned down. Beckford promptly rebuilt Fonthill IV., called by Colt Hoare “Fonthill Splendens†and the grounds also were laid out on a lavish scale.
At Fonthill IV. William Beckford II., the Eccentric, was born in 1760. He, it was who chose a site on Hinckley Hill, S.W. of Fonthill IV., and on it built Fonthill Abbey. Here, in December, 1800, came Lord Nelson with Lord and Lady Hamilton. The visitors stayed at Fonthill House but the theatricals to which Lady Hamilton contributed took place at Fonthill Abbey.
Later Fonthill IV. was demolished and Beckford II. lived at the Abbey (1801-1822). “His neighbours avoided him, his visitors were few and an air of mystery enveloped the place . . . â€
At last, in 1821, owing to financial losses, he decided to leave the Abbey. The property was sold to John Farquhar and Beckford went to live at Lansdowne House in Bath.
A few years later the property again changed hands. There was now no Fonthill House and the way was clear for the houses of George Mortimer and Alfred Morrison on the old site, the flat ground near the lake, for the Marquis of Westminster’s near the Abbey and for the house of Hugh Morrison on Little Ridge.
