Aldenham is a village and civil parish in Hertfordshire, 3.5 miles (5.6 km) north-east of Watford and 2 miles (3.2 km) southwest of Radlett. It was mentioned in the Domesday Book and is one of Hertsmere's 14 conservation areas. This secluded little village has eight pre-19th century buildings that are listed buildings and the parish itself is largely unchanged, though buildings have been rebuilt, since Saxon times when the majority of the land was owned by the abbots of Westminster Abbey.
In the Index of Multiple Deprivation, the ward of Aldenham East was ranked the least deprived ward out of 8414 in England, while Aldenham West also featured among the least deprived three per cent in the country. Radlett forms the eastern part of the civil parish.
For most recorded history Aldenham was administered together with the nearby settlement of Radlett (or at least, the Western part of that village), which until the modern era was of comparable size.
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.
Round Bush is also on the B462 road, and lies immediately to the east, less than 300 metres (980 ft) away. Its population size and number of buildings make it a smaller settlement. However, Round Bush has one pub A more average (smaller) size hamlet, the centre with the vast majority of the homes due to surrounding cultivated larger sized farms – is where three roads meet at a public house.
This is the largest hamlet, and is 0.8 miles (1.3 km) southeast, it is slightly larger in population size than the village itself, see Letchmore Heath.
Crossways Cottage is just northeast of the Infant School and almshouses and is opposite the junction of the lane leading to Letchmore Heath. 
Close to the church stand a number of buildings of historical interest. The earliest of these is Aldenham Social Club – a late medieval hall house dating from around 1500. To the west of the churchyard stands Church Farm House (16th – 18th century) and to the east the old vicarage (now two dwellings), a fine example of early 18th century red brick architecture.
Sporting and leisure amenities
The golf and country park is central to the village in Church Lane.
Aldenham Country Park is council-owned land which is some distance away from the old village closer to the two southern hamlets it has a 60 acres (24 ha) lake, Hillfield Reservoir and is south of Letchmore Heath.
Directly south of the country park is Aldenham Sailing Club which uses Aldenham Reservoir a 50 acres (20 ha) wide boxing glove shaped lake next to Elstree.
Aldenham Cricket Club (ACC) was founded in 1972, Aldenham has been playing cricket for over 40 years at the Parish. Hosted kindly by the Aldenham Social Club, Aldenham Cricket Club has won the Watford Observer Plate on two occasions, the Hertfordshire Village Trophy & won the league in the last 2 years.
