The city renowned for its annual music festival that draws visitors from around the world is Glastonbury.

The festival not only features music but also encompasses art installations, performances, and other cultural activities, making it a significant cultural event that attracts a global audience.

This festival takes place in the outskirts of Glastonbury, which has a rich cultural and historical background, often associated with traditions and legends. The sheer scale of the festival, with more than 200,000 attendees, underscores its prominent status in the music world. Other cities, although they host various music events and festivals, do not have a singular festival with the same level of international recognition as Glastonbury's.
