The buildings were generally of a modest size, an exception being Barrington Court in Somerset, the Trust's first large country house.:34-36 Two of the sites acquired by the Trust in its early years later became nature reserves: Wicken Fen in Cambridgeshire and Blakeney Point in Norfolk, both purchased with the help of a donation by naturalist and banker Charles Rothschild.:36-37 White Barrow on Salisbury Plain was the Trust's first archaeological monument, purchased in 1909 for £60.
