The parish of Aldenham historically had two main settlements, being Aldenham itself where the parish church is located, and
Radlett on
Watling Street, one of the main roads in the area. The two settlements were of comparable size until the modern era. Since
Radlett railway station opened in 1868 Radlett has grown to be significantly larger than Aldenham village, but it remains part of the parish. Aldenham Parish Council has its offices in Radlett. The parish also includes
Letchmore Heath. In 1086 in the Domesday Book, Aldenham parish appears to have straddled the boundary of two ancient hundreds: Danish Hundred (East of North Watford, North of Patchetts Green) and
St Albans Hundred (South of Hanstead). The Domesday surveyors were recording a property ownership dispute that had been ongoing for three centuries regarding heavily forested land. The Church of St
John the Baptist in Aldenham village is seven hundred and fifty years old and there is good reason to believe that an earlier Saxon church stood on the site. After the
Reformation the lands were sold off to the highest bidders and Aldenham is probably smaller today than it was 500 years ago. In 1940, a German air attack damaged stained glass and removed the "
Hertfordshire Spike" – the spire on the top of the tower. Restoration work was completed in 1951. Both the church and the village have been used in many films, advertisements and television programmes, being within easy travelling distance of
Elstree Studios. These have included the film
Confessions of a Window Cleaner,
BBC television series
Pathfinders, and the
Coldplay music video for "
Life in Technicolor II", to name but a few. Although it gave its name to the Aldenham Bus Works owned by London Transport,
Aldenham Works was actually located at nearby Elstree. ==Hamlets==
