Carew Manor House, originally built in the 15th-16th centuries, was the home of Sir Francis Carew, whose gardens were famous in the 17th century. They included waterworks and an orangery, which was said to be the first in England. All this has gone but several 17th and 18th century walls survive, including a long orangery wall with blank arcading divided into pairs by pilasters on the north face.
The Manor House is now a school. Guided tours take place on a number of summer Sunday afternoons. Call 020 8770 4781 for details.
