Hamburger Bahnhof in Berlin has reunited five artists who once kept studios in the warehouses next to the museum, marking the institution's 30th anniversary with the exhibition "Next Door." The opening took place on 8 October 2026, with the show on view from 9 October until further notice. Tacita Dean, Bruce Nauman, Thomas Demand, Olafur Eliasson, Henrik Håkansson and Tomás Saraceno all worked in the former industrial and railway buildings beside Hamburger Bahnhof in the early 2000s. Those spaces — relics of Berlin's railway past — were later absorbed into the museum, and two decades on the artists meet again with new, large-scale works in the Rieckhallen. Dean, Nauman, Demand, Eliasson, Håkansson and Saraceno were among the first generation to use the raw industrial rooms, and each has since built an international career, making the reunion a snapshot of how far both the artists and the institution have travelled. The reunion is staged by Hamburger Bahnhof director Sam Bardaouil together with curator Ulya Soley, and the opening took place in the artists' presence. The museum, opened in 1996 in a former 19th-century railway terminus, is the Nationalgalerie's largest house and has long used its vast halls for ambitious installation-based projects. "Next Door" is less a conventional group show than a homecoming built around shared history: the title points to the neighbouring buildings where the six once painted, built and filmed. For a museum that has become one of Europe's leading addresses for contemporary art, the project turns its own past — the studios, the warehouses, the early-2000s moment — into the subject of the exhibition.
