25 Years of Sommerwerft –

an anniversiry, celebrating the river

In the summer of 2026, we celebrate the 25th anniversary of Sommerwerft—an international theater festival by the river. Since its inception, the festival has evolved from an independent grassroots initiative into an integral part of Frankfurt’s cultural landscape; today, it stands in the shadow of the European Central Bank while remaining firmly rooted along the Main. For this anniversary year, Sommerwerft once again invites everyone to enjoy 17 days of culture on the banks of the Main—a place where people have long gathered to linger, listen, and connect within an open space for exchange and social interaction.

Our gift for the 25th anniversary:

Blue Lab 2026 – The Ocean Starts… in Frankfurt!

As part of the Sommerwerft festival, from July 29 to August 2, the Blue Lab is transforming the banks of the Main River into an open, inclusive space for learning and discovery. Under the motto “The Ocean Starts… in Frankfurt!”, visitors embark on a symbolic journey from the sources of the Main and Rhine rivers to the North Sea—a “source-to-sea” perspective that highlights the close connection between rivers and oceans. The program follows the natural water cycle—from the source through rivers and wetlands to coasts, estuaries, and the ocean—culminating on August 2 in a collective celebration of water. Central to the event are the values ​​of respect, responsibility, collectivity, democracy, and inclusion.

Culture for all – with everyone!

Since its inception, Sommerwerft has stood for an open, accessible theater culture that deliberately takes place away from established stages. The festival fosters social interaction and intercultural dialogue, thriving on the strong volunteer commitment that serves as both the foundation and the backbone of the project. Today, more than two decades after its launch, Sommerwerft is a fixture of the independent theater scene. Each year, around 200 artists and groups from the fields of music, dance, theater, poetry, and performance create a diverse program. With over 110,000 annual visitors, Sommerwerft ranks among Germany’s largest open-air theater events, bringing theater in public spaces to a wide audience.
