Winston Churchill's father called the view of Blenheim Palace, its lake and the Grand Bridge the finest in England. It certainly all looks grand from the edge of this beautiful, man-made lake. When Blenheim Palace was first built, the lake was not much more than a marshy stream. It was 'Capability' Brown who imagined a grand lake as part of his great vision for Blenheim Park. In 1764, he dammed the River Glyme, creating the lake and its series of beautiful cascades. Today, Blenheim Park is a Site of Special Scientific Interest due, in part, to the lake's importance for breeding and wintering birds.
