Penhallam is the site of a fortified manor house near Jacobstow in Cornwall, England. There was probably an earlier, 11th-century ringwork castle on the site, constructed by Tryold or his son, Richard fitz Turold in the years after the Norman invasion of 1066. Their descendants, in particular Andrew de Cardinham, created a substantial, sophisticated manor house at Penhallam between the 1180s and 1234, building a quadrangle of ranges facing onto an internal courtyard, surrounded by a moat and external buildings. The Cardinhams may have used the manor house for hunting expeditions in their nearby deer park. By the 14th century, the Cardinham male line had died out and the house was occupied by tenants. The surrounding manor was broken up and the house itself fell into decay and robbed for its stone. Archaeological investigations between 1968 and 1973 uncovered its foundations, unaltered since the medieval period, and the site is now managed by English Heritage and open to visitors.
