Syon House - Syon Park

Syon Park borders the Thames, looking across the river to Kew Gardens and near its banks is a tidal meadow flooded twice a day by the river. It contains more than 200 species of rare trees. Although the park and lake were designed by Capability Brown in 1760, their character today is nineteenth century. The circular pool has a copy of Giambologna's Mercury.

The Great Conservatory in the gardens, designed by Charles Fowler in 1828 and completed in 1830, was the first conservatory to be built from metal and glass on a large scale. The conservatory appeared (as Heaven) in the original 1967 Dudley Moore-Peter Cook version of Bedazzled, having already featured prominently in John Boorman's first feature film Catch Us If You Can (film) (1965, ostensibly a vehicle for the Dave Clark Five), was shown in a dream sequence in Meera Syal's 1993 film Bhaji on the Beach and was also the setting for the music video to The Cure's 1984 single "The Caterpillar", directed by Tim Pope.

Henry Percy, 11th Duke of Northumberland, who was head of the family from 1988 to 1995, was noted for planting many trees in the grounds of Syon.

In 2002, the English poet Geoffrey Hill released a booklength poem, "The Orchards of Syon", to much acclaim. "The Orchards of Syon", focuses on the history of the region and in particular on the orchard of rare trees first planted in Syon Abbey.

Robert Altman's 2001 film Gosford Park was partly filmed at Syon House.

The London Butterfly House was based in the grounds of Syon Park from 1981 until its closure on 28 October 2007 due to the Duke of Northumberland's plans to build a hotel complex on the land.

In 2004, planning permission was granted for the deluxe £35-million Radisson Edwardian Hotel, but this was not built. Instead, work started in December 2008 on a Waldorf Astoria hotel, which opened in March 2011. In 2002 an annual archaeological dig was initiated originally by the Channel 4 television Time Team programme, to excavate the remains of the lost abbey, the annual dig is now undertaken by Birkbeck College part of the University of London The annual dig is back up by a permanent exhibition in the undercroft In November 2010, the results from an archaeological dig made two years before on the site of the new hotel were reported, with the excavations uncovering the remains of a Roman village that existed in what was then the rural outskirts of Londinium. Artefacts uncovered included 11,500 pottery fragments, 100 coins and pieces of jewellery. Some of finds remain unexplained, such as the discovery of skeletons "buried in ditches placed on their side". Although the skeletons date from the Roman period, this burial practice was said by the senior archaeologist to be "more suggestive of unknown prehistoric rites than Roman practice".

Syon Park is a Site of Special Scientific Interest.
