Severndroog Castle is a folly situated in Oxleas Wood, on Shooter's Hill in south-east London in the Royal Borough of Greenwich. It was designed by architect Richard Jupp, with the first stone laid on 2 April 1784.
It was built to commemorate Commodore Sir William James who, in April 1755, attacked and destroyed the island fortress of Suvarnadurg (then rendered in English: Severndroog) of the Maratha Empire on the western coast of India, between Mumbai and Goa. James died in 1783 and the castle was built as a memorial to him by his widow, Lady James of Eltham.
Designated a Grade II* listed building in 1954, the Gothic-style castle is 63 feet (19 m) high and triangular in section, with a hexagonal turret at each corner. From its elevated position, it offers views across London, with features in seven different counties visible on a clear day.
In 1797, the tower was used by General William Roy in his trigonometric survey linking England and France; a 36-inch theodolite (now in London's Science Museum) was installed on its summit. In 1848, the Royal Engineers used the castle for their survey of London.
Following Lady James' death in 1798, the building passed through the hands of various landowners, including John Blades, a former Sheriff of London, a Mr Barlow (ship owner) who built nearby Castle Wood House, and Thomas Jackson (a railway and docks contractor of Eltham Park). In 1922, the tower was purchased by London County Council and it became a local visitor attraction with a ground-floor tearoom serving drinks and cakes. In 1986, when the GLC was abolished, responsibility for Severndroog passed to Greenwich Council.
In 1988, the local council could no longer afford the building's upkeep and it was boarded up. In 2002, a community group, the Severndroog Castle Building Preservation Trust, was established. In 2004, it featured in the BBC TV series Restoration (presented by Griff Rhys Jones, Ptolemy Dean and Marianne Suhr, producer-director Paul Coueslant) - with the aim of gaining support for a programme of work to restore the building and open it to the public.
The entire castle, or just the William James room on the second floor, can be hired for weddings, functions, private events and meetings. The castle is open to the public on Thursdays, Fridays and Sundays from 12:30 to 16:30 (opening times may differ during Winter).
