Thousands of islanders are expected to turn out for the event involving craft stalls, fairground rides, live musicians and DJs, and the Norman Market.
Included in the celebrations will be the pilgrimage to Elizabeth Castle on Sunday, with walkers gathering at the Town Church at 13:00.

“This really is one of the highlights of the Parish’s events calendar… I look forward to seeing islanders young and old making the most of our town,” said Town Events Manager Connor Burgher.
