The Glastonbury Tercentennial Labyrinth resides in the churchyard of St John the Baptist on the High Street. It is a grass labyrinth of the classical seven circuit design: its path delineated by blue lias stonework, a local stone present in Glastonbury Tor built in 2007.
Students from St Dunstan’s school dug the trenches under the supervision of a local builder and many people from all walks of life and spiritual persuasions volunteered their time to help in its construction. Many local residents helped to finance the project, including bookshops, organisations, and Glastonbury Town Council.
The Labyrinth was created through the efforts of Sig Lonegren, a Glastonbury geomancer and author. It was proposed in 2002 that a labyrinth be constructed to mark the 300th year since Glastonbury received its town centre charter from Queen Anne. A committee was set up and included the town’s mayor, the vicar and the curate of St John’s the Baptist, and Sig, who took on the role of co-ordinator. Several sites were chosen in succession and permission gained from appropriate authorities, but then were turn down on objection from residents living adjacent to the sites. Just when it seemed that the project would never get off the ground, the Reverend Maxine Marsh had the idea to ask her congregation about building it in the churchyard. After consultation, they gave their approval. Permission was then sought from British Heritage, Mendip District Council, and up through the ecclesiastical hierarchy.
The labyrinth contains four plaques that commemorate four of Glastonbury's Saints - Mary, Bridget, Dunstan and Joseph of Arimathea.
