Colnbrook is a village in the unitary authority of Slough, in Berkshire, England. It has formed part of the Colnbrook with Poyle Parish since 1995, previously having been part of Iver Parish in Buckinghamshire.
Mentioned in William the Conquerors Doomsday Book, Colnbrook sits on a tributary to the main Colne river hence “Colnbrook”. Coaching inns were the village’s main industry. In 1106 the first one was founded by Milo Crispin, named “The Hospice” (now the Ostrich Inn).
By 1577 Colnbrook had no fewer than ten coaching inns. Colnbrook’s High Street was on the main London to Bath road and turn off point for Windsor and was used as a resting point for travellers.
One 17th century landlord Jarman of the Ostrich Inn installed a bedside trap door in one of the bedrooms, and 60 of his richer clients were dropped into a vat of boiling water. Their bodies were then disposed of in the Colne River. Jarman was hanged for robbery and murder.
