The Pyramid Stage was first used at Glastonbury in 1971.
That year’s event was called Glastonbury Fayre and was organised by Andrew Kerr and his collaborators, including Michael Eavis, Arabella Churchill and stage designer Bill Harkin. Harkin conceived the first Pyramid Stage as a one-tenth-scale replica of the Great Pyramid of Giza. It was built from scaffolding and metal sheeting and placed over what was described as a “blind spring”.
The 1971 festival took place from 20 to 24 June and was free to attend. Its performers included David Bowie, Joan Baez, Traffic, Fairport Convention, Hawkwind, Melanie and Gilberto Gil. The stage became the festival’s defining landmark, although it has been rebuilt and redesigned several times.
The year 1970 is an understandable wrong answer because it was the date of the first festival at Worthy Farm. However, the Pyramid Stage itself debuted at the following festival, in 1971. A later permanent structure was built in 1981, and the stage was rebuilt again after a fire destroyed it in 1994.
