The exact date of construction is not known, but is believed to have started in the 15th century and was definitely before 1574, when the initials of the owner George Perceval, the father of
Richard Percivale, were added to the chimney piece in the library. One of his descendants Richard Percivale (or Perceval) contributed to the English response to the plans for invasion by the
Spanish Armada by deciphering
Spanish documents for
Queen Elizabeth. He employed Arthur James Stratton, an expert on Tudor architecture to reconstruct the west wing. before being returned by Charles Evans to Upper Langford in 1923. The rebuilding included the erection of a tower. The first version looked similar to a
lighthouse and was changed to one of Tudor appearance which was incorporated into the south wing. ==Architecture==
