Which entity is charged with preserving the environment and historical constructions?

The National Trust is all about protecting Britain's natural and built heritage. Think of them as the guardians of beautiful landscapes, historic houses, and important archaeological sites. They were founded way back in 1895, at a time when there was growing concern about the loss of open spaces and historic buildings due to industrialization and development. Their mission is to preserve these places for future generations to enjoy. They do this by owning and managing a vast portfolio of properties, from coastlines and forests to castles and stately homes. The other options listed simply have different focuses. The NSPCC is dedicated to child protection, Age UK supports older people, and the PDSA provides veterinary care for animals in need. While all are important charities, only the National Trust has the specific remit of preserving the environment and historical constructions. So, if you hear about a place being protected for its historical or environmental value, chances are the National Trust is involved.
Imagine a nation entrusting the safeguarding of its heritage to this organization.
