Amsterdam will hold a big party on the A10 Ring Road on Saturday, 21 June 2025, as part of its 750th anniversary celebrations. The city will close the ring road for the party. “A large number of festive activities will take place on almost 15 kilometers of highway that day, with music, sports, theater, dance, and more,” Amsterdam said on Tuesday. A 750th anniversary only happens once, Mayor Femke Halsema said. “That’s why we’re celebrating big, at a fantastic location, on the longest day of the anniversary year. Everyone is welcome to celebrate Amsterdam’s birthday on June 21.”
