If you love old castles and historic houses then are you in the National Trust or English Heritage?
If you are not a member then I will give you an overview of each organization, the National Trust first in this append, then English Heritage in my next append.
The National Trust is an independant organization (a charity) that helps to preserve houses, gardens, other buildings, coastlines, beautiful areas and so on.
They own hundreds of houses and gardens all over the UK (England and Wales only I think) including Waddesdon Manor, Sissinghurst, Stourhead, Chartwell (Winston Churchill's home) and hundreds more.
They also own thousands of acres of parts of England and Wales (Lake District, Cornwall, Snowdonia etc) and also miles of coast line (to stop it being built on).
You have to pay to be a member (yearly), but while you are a member you can get into EVERY National Trust house and garden for FREE, as many times you like in that year.
You can also park for free in any National Trust car park (very useful if you visit the Lake District or Cornwall where the NT own many car parks and usually charge to park).
You also get a yearly NT Guide to every property they own to help plan your visit, and a quarterly magazine showing what the NT are doing.
I think anyone who cares about preserving the history and beauty of this country should be a member of the National Trust.
