“Vert between four Oak Trees eradicated Or a Fesse wavy Argent charged with a wavy Gules overall upon a Pale also Argent a Fasces Sable”

The Coat of Arms was designed for the Parish in 1983 and incorporates many local references.

The oak trees on a green background are allusions to the rural nature of the Parish. In addition the “eradicated” – i.e. uprooted – oak trees also form part of the Arms of the Lords Rendelsham, since 1799 Lords of the Manor of Aldenham.

The central element is an axe surrounded by a bundle of rods, a Fasces, which since Roman times has been a symbol of magisterial and civic authority. The axe also appears in the Arms of Lord Aldenham whose son, Kenneth, was the Vicar of Aldenham and the first Chairman of the Parish Council.

The wavy red line represents Tykes Water, once an important mill stream or leat, the waters of which turned red as they collected drainage water from the surrounding clay land. Some say that this is the origin of the village’s name, a red mill stream, leat.

Finally the broad vertical line and wavy horizontal lines, all which represent respectively Watling Street and the minor country roads crossing the Parish. This also ties into another theory on the name for Radlett, i.e. “a junction of roads”.
