Following the Norman Conquest, Horley is not named in William 1st's Domesday Book as it is thought to be included within the northern manor returns. After the Dissolution of the Monastries in 1539, Horley Manor passed to Henry VIII who gave or sold it to various people until 1602, when it became the property of Christ's Hospital in London. A map of its purchase was produced in that year, the original of which is held today by the Guildhall Library in the City of London. This map clearly shows that Horley consisted of three separated settlements around the western and northern edges of a huge open common.
One by the Church, parts of which are thought to be 14th century, along with today's Six Bells Public House of 15th century origin; another where the Watermill once stood by the River Mole; and the third, along the northern boundary of the common (today called Horley Row) where several other properties can be seen, dating back to the 15th and 16th centuries.
