In September 1976, four teenagers answered an ad on a Northside noticeboard and changed the course of rock music forever. Fifty years later, the world is returning to where it all began. Welcome To The Northside, in association with the U2 Dublin Fan Club, proudly announces U250 — a landmark three-day fan festival celebrating 50 years of U2, taking place across Dublin from Friday 25th to Sunday 27th September 2026. Conceived as a global “Dublin pilgrimage,” U250 is expected to draw fans from across Ireland and around the world — honouring the Northside roots of U2 and the festival’s organisers while activating iconic venues across the city — and transforming Dublin into a weekend-long celebration of the band’s music, history, and cultural impact.
