Bhaktivedanta Manor is a Gaudiya Vaishnava temple set in the Hertfordshire countryside of England, in the village of Letchmore Heath near Watford. The Manor is owned and run by the International Society for Krishna Consciousness (ISKCON), better known as the Hare Krishna movement. It is ISKCON's largest property in the United Kingdom, and one of the most frequently visited Radha Krishna temples in Europe. The house is listed Grade II on the National Heritage List for England.Previously known as Piggott's Manor, the property was donated to the Hare Krishna movement in February 1973 by former Beatle George Harrison, after the Radha Krishna Temple in central London had become inadequate to house the growing number of devotees. The donation included 17 acres of land, following which the estate was extended through the acquisition of neighbouring properties. Harrison had a close relationship with ISKCON's founder-acharya, A.C. Bhaktivedanta Swami Prabhupada, and visited him at the Manor on several occasions. Beginning in 1981, ISKCON was engaged in a campaign to save Bhaktivedanta Manor from closure as a public temple, as the popularity of the site led to increased traffic through Aldenham. After a series of court hearings and appeals, the Department of the Environment granted permission for the building of a road bypassing the village in 1996. With the improved access, the Manor hosts up to 60,000 visitors for annual religious festivals such as Janmashtami.

Haberdashers' Boys' School (also known as Haberdashers', Habs, or Habs Boys), until September 2021 known as Haberdashers' Aske's Boys' School, is a public school for pupils age 4 to 18 in Elstree, Hertfordshire, England. The school is a member of the Headmasters' and Headmistresses' Conference and the Rugby Group. The school was founded in 1690 by a Royal Charter granted to the Worshipful Company of Haberdashers to establish a hospital for 20 boarders with £32,000 from the legacy of Robert Aske (equivalent to approximately £5M in 2019). The school relocated in 1903 and currently occupies 104 acres of green belt countryside in Elstree. At its centre is Aldenham House, a Grade II* listed building, that was formerly the seat of the Lords Aldenham and home to Vicary Gibbs MP. While the school once offered boarding to some students, it has since become an all-day school, with the boarding quarters having been converted to offices. In 2017, it was the Sunday Times independent school of the year. In 2012 and 2016, it was the top independent boys' school in the country. Approximately 20% of its students go on to study at the universities of Oxford and Cambridge, putting the school at 10th place in the country in terms of Oxbridge admissions. It has also sent boys to top US universities, including Harvard and Stanford. Haberdashers' Boys' School frequently tops the league tables and rarely falls out of the top 10. In 2014, The Telegraph placed the school at 8th in the country for A-Levels – with 80.87% of students achieving the A*–A grades. In 2015, the Sunday Times named Haberdashers' the best school in England owing to its results and resources.As a result of discussion in 2021, Robert Aske's name was dropped from the boys' and girls' Haberdashers' Schools in Elstree, although it was retained by their governing body. At the same time, the school's motto was changed, from "Serve and Obey" to "Together, boundless". The motto reflected the Christian values of the school, not its links with slavery, but was seen to be inappropriate following the discovery. The student body protested against this decision but was unsuccessful in its appeal.

Aldenham House is a former country house in Elstree, just south-east of Aldenham village and west of Borehamwood, Hertfordshire, England, which was the seat of the Gibbs family, who were the Barons Aldenham. The site today accommodates the Hilfield Reservoir, the Lister Institute, the Haberdashers' Boys' School and Haberdashers' School for Girls. The house was built c.1672 for H. Coghill the Younger and was acquired, renovated and extended c.1870 by the wealthy Hucks Gibbs, 1st Baron Aldenham. In 1932 the estate was sold after the death of its then occupant Vicary Gibbs, a wealthy financier, MP and avid plant collector who had amassed a larger collection of Chinese flora than the Royal Botanic Gardens Kew. Gibbs never married, and most of the plant collection was auctioned after his death. The house and grounds became a country club until the Second World War, when it was requisitioned by the BBC for use as an overseas broadcasting station. After the war the house stood empty until occupied by the Haberdashers' Boys' School in 1961. While building works for the new school were in progress, MGM shot the 'carry-on' style film Kill or Cure in the entrance hall and on the front lawn. The frontage and grounds have since appeared in a number of episodes of several 1960s television programmes including The Avengers and The Saint.Aldenham House is a Grade II* listed building.
