Heritage Open Days celebrates England's fantastic architecture and culture by offering free access to properties that are usually closed to the public or normally charge for admission. Every year on four days in September, buildings of every age, style and function throw open their doors.
It is a once-a-year chance to discover hidden architectural treasures and enjoy a wide range of events and activities which bring to life local history and culture.
For a full list of properties that are open in Cornwall, please visit the Heritage Open Days website.
