- To be a champion of volunteering. Our volunteers nationally contribute 3.1 million hours per year which equates to a notional value of more than £25 million.

How we deliver these aims
We protect over 700 miles of coastline and in total we look after 617,500 acres (250,000 hectares) of countryside, moorland, beaches and coastline. Amongst the historic properties in the Trust's care are 166 fine houses, 19 castles, 47 industrial monuments and mills, 49 churches and chapels, and 35 pubs and inns. The millions of objects in the care of the National Trust reflect its diversity. Conservation staff and volunteers care for an astonishing range of structures and contents, from 26 sets of samurai armour, or 19 magnificent paintings by Turner, to the Oscar awarded to George Bernard Shaw, the national collection of lawnmowers, 57 meat strainers or a photograph album the size of a postage stamp.Who benefits from our work
