Visit a monument to the future

With the ever-growing JS ecosystem, it’s only appropriate that we are hosting React Day Berlin in Kosmos, the amazing Space Age theatre from the 1960s. It is situated in the hip neighborhood of Friedrichshain full of great restaurants, bars, clubs and little shops, and the building was built with unconventional visionaries in mind.

Explore a major EU tech hub

Berlin, Germany’s capital, is one of the busiest European tech centers, and the best React talent gravitates towards the city. With an international airport and modern train infrastructure, you’ll easily get there from anywhere.
