In 1855, Thomas Cook, the trailblazing tour operator, expanded his horizons with the first overseas tour from Harwich to Paris. Departing from his UK-centric excursions, Cook's parties explored Antwerp, Brussels, Cologne, Heidelberg, Strasbourg, and Paris during the International Exhibition. This journey marked a pivotal moment, introducing travelers to cultural treasures at the Louvre and the Champs-Élysées halls. Cook's commitment to broadening travel experiences laid the groundwork for the global tourism legacy he would later create, despite the recent collapse of his namesake company.
