Radlett is a large village in Hertfordshire, England, between Elstree and St Albans on Watling Street, with a population of 10,060.

Radlett lies in the valley of Tykes Water, a stream that runs north from Aldenham Reservoir to the River Colne.

The Catuvellauni tribe settled in parts of Hertfordshire, near St Albans and Wheathamstead in about 80BC, although no trace of settlement has been found in or near Radlett itself.

The name Radlett appears to come from the Old-English rad-gelaete meaning a junction of the roads and it is likely that the settlement grew at the point where the ancient route from Aldenham to Shenley crosses Watling Street.

[10] Roman-era clay pits are still in evidence at the southern end of the village, in the area around Cobden hill and Tabard RFC.

In addition, there is evidence of a Roman villa with a bath building, barn and tile kiln dating from 2nd to 4th century AD, in the area of Netherwylde Farm.

[13] It is known that in the thirteenth century, gallows were erected jointly by the Abbots of Westminster and St Albans 'in a certain spot called Keneprowe' (now Kemp Row), for trials conducted at Aldenham.

[12] Radlett seems to have consisted of two farms: Darnells (first mentioned in 1358) and Gills Hill on the west side of Watling Street; and the estates of Aldenham Lodge, Newberries and Organ Hall on the east, plus Newlands (first recorded in 1291) and a few cottages.

[citation needed] On 8 December 1865 the Ecclesiastical Parish of Radlett was created out of the eastern part of Aldenham and this marks the start of the modern history of the village.

The Handley Page Victor bomber prototype was built here, with the main runway being extended in 1952 to allow flight testing, and there is now a road on this site named in its honour next to a DPD depot.

[16] In 1977 Eddie Kidd the stunt rider jumped over 14 London Double Decker buses at the former Radlett Aerodrome.

[citation needed] In 2005, and 2006, there was a large campaign[18] in the village, and surrounding areas to save the Fire Station, which was opened 100 years ago.

[23] Radlett is classed as a post town by the Royal Mail, corresponding to the WD7 postcode district, which also covers the neighbouring village of Shenley.

Radlett is part of Transport for London's (TfL) Oyster card and contactless payment travel system.

[30] Radlett CC, established in 1884, has a significant success record, with 8 Hertfordshire Cricket League championship titles to their name.

It is now the training facility of Middlesex County Cricket Club and the ground hosted all their home Royal London Cup fixtures in 2019.
