The 1971 Pyramid Stage was a replica of which ancient structure?

The 1971 Pyramid Stage was a one-tenth replica of the Great Pyramid of Giza.

The structure was conceived by Bill Harkin for the 1971 Glastonbury Fayre, the second major festival at Worthy Farm. It was built from scaffolding and metal sheeting, creating the distinctive pyramid form that eventually gave Glastonbury’s main stage its enduring name. The stage stood over what organisers described as a “blind spring”, reflecting the festival’s blend of music, counterculture and alternative spiritual ideas.

The 1971 structure was very different from the modern Pyramid Stage, which is a much larger engineered concert structure. It was nevertheless the first incarnation of Glastonbury’s most famous stage and established the pyramid design as part of the festival’s identity. The event itself was free and included David Bowie, Joan Baez, Traffic, Fairport Convention, Hawkwind and Melanie. The Parthenon, Colosseum and Stonehenge are all plausible ancient landmarks, but none was the model for this stage.
