Landmark Trust is a group of very nice people who take old buildings that nobody lives in anymore and make them happy places again. They do this by repairing things that are broken and making sure the buildings are safe for people to live in. These buildings can be really old, like maybe even older than your grandma! Landmark Trust makes sure to keep them looking very special and pretty, like they did a long time ago. Then, they let people come and stay in these buildings for a little while, like going on an adventure. People that stay in these buildings get to see what it was like a long time ago and have lots of fun too!
