Opbouwdagen 2026
Rotterdam, a safe haven?
During the Opbouwdagen from May 15 to 18, you can explore the post-war reconstruction architecture of Rotterdam.
This year, the festival revolves around the theme: “Rotterdam, a safe harbor? Then and now. From a moorage for ships to safe places to stay.” During the Opbouwdagen, you can join various guided tours showcasing reconstruction art and architecture. You can also take part in the new tower experience at the Laurenskerk: 365 steps through time. Over the weekend in May, two lectures will take place at Museum Rotterdam. Paul Groenendijk will speak about the history of the Coolhaven district, and there will also be a lecture on the history of the many seamen’s churches in Rotterdam.
