When Lovel's great grandson lost the family's estate in the 1460s, there followed a rapid succession of owners and tenants.
In 1547 the castle was sold to Sir Thomas Arundell of Lanherne. The castle was confiscated (again) when Sir Thomas was executed for treason in 1552,
but was later acquired by his son, Sir Matthew Arundell, in 1570. By this time the house would have seemed old fashioned and uncomfortable by the standards of the day,
and it therefore received an Elizabethan 'makeover': with much remodelling and modernisation being undertaken.
Doorways were redesigned, and windows enlarged to let in more light; a new gallery was added;
and the house was decorated and furnished to a very high standard.
