Colnbrook in 1836
Colnbrook is on the high western road, 17 miles from London, in the hundred of Stoke, and in the three parishes of Langley, Horton, and Iver, (Bucks,) except a small part which is in the parish of Stanwell, Spelthorne hundred, county of Middlesex. The town consists of one long street of neat respectable-looking houses. The Coln here flows in four channels, crossed by as many bridges ; and from this circumstance, combined with the agreement of its distance from London, Camden and others are inclined to regard it as the Pontes of the Itinerary of Antoninus ; but in the map of Ancient Britain, published by the Society for the Diffusion of Useful Knowledge, Pontes is fixed at Staines. An ancient chantry chapel at Colnbrook, which continued to be used after the Reformation, was endowed by private benefaction in 1682. This old chapel, which was in Langley parish, has since been pulled down and rebuilt on a different site in the parish of Horton. The market was on Tuesday, but is now discontinued. There are still two fairs, on the 5th of April and 3rd of May. The town was incorporated in 1543, by the style of the bailiff and burgesses of Colnbrook.
