The Grove is a large hotel in Hertfordshire, England, with a 300–acre (1.2 km2) private park next to the River Gade and the Grand Union Canal. It touches on its north-west corner the M25 motorway and remains a small part in Watford. The estate is situated within three different settlements; most of the land and all of the mansion itself are in the civil parish of Sarratt, and also in the ecclesiastical parish of Langleybury, while the estate lies within the post town of Rickmansworth. Originally built as an English country house on the site of a medieval manor house, The Grove served as the family seat of the Earls of Clarendon (second creation), the Villiers family, from 1776–c.1920. Since its Georgian construction, The Grove has been altered and extended four times by a number of noted architects, including Surveyor of the King's Works, Robert Taylor. Following the increase in estate duty in 1914, the Villiers Family sold off the house and estate. Today it is in use as a luxury hotel and golf course. The Grove often hosts major international events, such as the WGC-American Express Championship in 2006, the 2009 G20 London summit, the 2013 Bilderberg Conference and the 2019 NATO Leaders' Meeting.

Hunton Bridge is a small settlement near Abbots Langley, Hertfordshire, England, with a historic royal connection. Its population in the 1991 census was 327. It is in the Three Rivers population of Langleybury. Hunton Bridge enjoyed its greatest prosperity during 1810-26, when the Sparrows Herne turnpike ran through the village. Prior to that date the turnpike had run along Gypsy Lane and Upper Highway. In 1810 it was rerouted along Old Mill Lane to the village, and up the hill to reconnect with Upper Highway. By 1826 the presence of the canal and the works associated with it had dried out the bottom land sufficiently for the turnpike to be rerouted along what is now the A41 avoiding the climb up Hunton Bridge Hill. Today the village is situated between the M25 London orbital motorway and a spur of the motorway leading to Watford. The A41 trunk road runs just west of the village. The Hunton Bridge filling station just off the Watford spur (Junction 19 of the M25) is a local landmark.
