Cadhay is approached by an avenue of lime-trees, and stands in an extensive garden, with herbaceous borders and yew hedges, with excellent views over the original medieval fish ponds. The main part of the house was built in about 1550 by John Haydon who had married the de Cadhay heiress. He retained the Great Hall of an earlier house, of which the fine timber roof (about 1420-1460) can be seen. An Elizabethan Long Gallery was added by John’s successor at the end of the 16th century, thereby forming a unique courtyard with statues of Sovereigns on each side, described by Sir Simon Jenkins as one of the ‘Treasures of Devon’.
