Hunton Park is a large country house and estate in Abbots Langley, in south west Hertfordshire in the United Kingdom.

Abbots Langley is a large village and civil parish in the English county of Hertfordshire. It is an old settlement and is mentioned (under the name of Langelai) in the Domesday Book. Economically the village is closely linked to Watford and was formerly part of the Watford Rural District. Since 1974 it has been included in the Three Rivers district.

Watford Tunnels are a pair of railway tunnels on the West Coast Main Line just north-west of Watford in Hertfordshire, Eastern England. The original was built in 1837 for the London and Birmingham Railway to the design of Robert Stephenson and is just over a mile (1.6 kilometres) long. When the line was widened in the 1870s, a second tunnel was built just to the east. Both tunnels had decorative portals and the south portal of the original tunnel is a Grade II listed building.

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.

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.
