Summer in the City Mainz 2026

Summer in the City is the umbrella concert brand with which mainzplus Citymarketing GmbH programs the main open-air summer events in Mainz. Over six weeks, a series of around ten to twelve major concerts takes place at three venues. Unlike traditional festivals, each concert is a standalone event with its own ticketing – the brand acts as a framework and marketing umbrella.

The venues are carefully selected. The Mainz Citadel on Jakobsberg, a baroque fortress complex with views over the city, serves as the main stage for larger concerts. The Volkspark Mainz offers a greener, more family-friendly atmosphere for selected highlights. The KUZ — Kulturzentrum Mainz is reserved for more intimate performances. This three-part division allows for an exciting mix of urban, park, and indie character.

The 2026 program is exceptionally dense and diverse. Confirmed acts include Element of Crime (June 6, KUZ), Deine Freunde (June 12), GUUDE! — its own regional festival on June 13 — Foreigner (June 14, the US rock band with their hits from the 1970s and 1980s), No Angels with their 25th-anniversary concert (June 18), British soul singer Joss Stone (June 20), Natasha Bedingfield (June 23), the electronic festival High Root Open Air with Milk & Sugar and The Disco Boys (June 26), US alternative icons Garbage (June 27), and concluding with German pop singer Nina Chuba in Volkspark (July 16).

With this program depth, Summer in the City offers a nearly continuous concert experience for the Mainz audience from early June to mid-July. Tickets start at €29.90 for the smaller formats; headliner tickets range from around €50 to €80, depending on the act.
