The summer of 2026 will once again bring a powerful wave of guitars to Cartagena. The Rock Imperium Festival will return on July 3, 4 and 5, 2026, taking place at Parque de la Cuesta del Batel and continuing to establish itself as one of the most important rock and metal events in southern Europe.

Leading the lineup are three major names in the genre. British legends Iron Maiden will headline one of the festival nights with what promises to be one of the most anticipated performances of the weekend. They will be joined by Swedish power metal giants Sabaton, known for their high-energy and epic live shows, as well as Dutch symphonic metal icons Within Temptation.

The lineup also brings together a wide range of international artists representing different styles within metal and hard rock. Among the confirmed bands are Mastodon, Anthrax, Testament, Trivium, Queensrÿche, Lacuna Coil, H.E.A.T and The Gathering, among many others completing the bill.

Since its first edition, the festival has continued to grow, becoming a key meeting point for metal fans in Spain and beyond. Its seaside location and carefully curated lineups featuring both legendary acts and contemporary bands have helped position it as a prominent stop on the European festival circuit.

With three days dedicated to heavy music in all its forms, Rock Imperium Festival will once again turn Cartagena into a gathering point for rock and metal fans from across Europe.

Tickets and festival passes for the 2026 edition are already available through the festival’s official channels.
