It is one of the oldest and most interesting sites in the borough. It is named after, and dates from the time of, the Knights Templar. They farmed about 650 acres (2.6 km2) of the estate in the 12th century, and established a preceptory where a number of brothers lived and ran the estate. After the Order was suppressed, the estate was given to the Knights Hospitaller of St John. They lost it when Henry VIII dissolved the monasteries and Queen Elizabeth I gave the estate to Robert Dudley.
The 13th century church and Old Hall, and 17th century almshouses survive.
