Parish of Holy Trinity, Hounslow , Church of England

The parish of Holy Trinity, Hounslow, was originally a chapel belonging to a friary at Hounslow. After the Reformation the ownership of the chapel passed to the manor-house but a living was endowed and permission was given for the chapel to be used by those parishioners of Isleworth and Heston who lived in Hounslow, which at that date was divided between those parishes rather than being a separate parish. The chapel itself was situated in Heston parish, and drew staff from both Isleworth and Heston parishes. By the 18th century a charity school was closely connected with the chapel, which was also used for baptisms and marriages of Hounslow residents.

In 1816 the vicar of Heston bought the chapel and had it rebuilt on the same site. The new building was opened in 1829. In 1835 a parish was finally assigned to the chapel, comprising Hounslow and parts of Hounslow Heath. The Bishop of London became the patron of the living.
