MoundThe largest artificial mound in Europe is Silbury Hill, near Avebury (Wiltshire). It covers 5 acres, 34 perches, and measures at the base 2,027 feet; its diameter at top is 120 feet; its slope is 316 feet; perpendicular height, 107 feet; and it is altogether one of the most stupendous monuments of human labour in the world. Alyattes, in Asia Minor, described by Herodotus, is somewhat larger than Silbury Hill. Source: Dictionary of Phrase and Fable, E. Cobham Brewer, 1894 More on Mound from Infoplease:
