What type of ownership is the national trust?

The National Trust is a registered charity and a membership organization in the UK, primarily focused on the conservation of historic sites, landscapes, and nature. It operates under a form of ownership known as "charitable ownership," meaning it is governed by a board of trustees and relies on donations, membership fees, and revenue from its properties to fund its activities. The properties and land owned by the National Trust are held in trust for the benefit of the public and future generations.
