The National Trust is a UK conservation charity set up over 100 years ago.  Its objective is to protect historic buildings and preserve green spaces.  They make wonderful places to visit.  My husband doesn’t care much for the houses, and I can only with a clear conscience declare a passing interest.  However we enjoy exploring the wonderful gardens & grounds and playing croquet when the sun comes out.  Every trip is also never complete without a delicious cream tea and trip to the National Trust gift shop.
