The Landmark Trust is a UK-based charity that focuses on preserving historic buildings and making them accessible for public enjoyment. Founded in 1965, it acquires and restores properties of architectural or historical significance, ensuring they are maintained for future generations. Visitors can stay in these unique buildings, which range from castles to cottages, allowing them to experience history firsthand. The trust also promotes education about heritage and conservation, encouraging appreciation for the built environment and its importance in cultural identity.
