Glastonbury is a large town located near Blytonbury, a big city. Although Glastonbury is quite small compared to its sibling city, the Glastonbury Tor is located here, which is a ley line terminal taken by witches to travel to Luna Nova Magical Academy.
During the events of "A New Beginning", Akko Kagari traveled to Glastonbury in order to reach Luna Nova, and stayed there for a little bit until she discovered where the Glastonbury Tor is. Akko then quickly left the town to head to the hills.
Andrew Hanbridge was in Glastonbury in "Chariot and Croix", and called Akko here to get her witch hat back, which she had left in the Cavendish Manor. After having a pep talk, Akko leaves the area when she notices a mob growing in the plaza of the town, forgetting to grab her hat again. The mob continues to grow angrier and Akko decides to investigate what's causing this to happen, searching through the alleyways of the town to find something related to this event.
- In "Chariot and Croix", when Andrew meets Akko in Glastonbury, there is a shop branded "Mark and Sponcer" in the background, which is most likely a reference to the real life shop chain "Marks and Spencers".
