Cologne Cathedral, free for centuries, became the latest major attraction to end no-cost access. The fee was introduced on July 1, according to a report from Traveller's Holiday Guide to Affordable Travel.
The trend extends beyond Europe: Japan's Mount Fuji now charges hikers, and in Istanbul the Hagia Sophia went from free to a 25 euro fee in 2024. Rome introduced charges for the Pantheon in 2023 and the Trevi Fountain in 2025.
Among still-free attractions highlighted is Berlin's East Side Gallery. This surviving section of the Berlin Wall is the world's longest open-air gallery, featuring more than 100 paintings across almost two kilometres. It has official heritage-protected status and is open 24 hours a day, drawing more than three million visitors annually. One of its most recognised murals is the "Fraternal Kiss" depicting Erich Honecker and Leonid Brezhnev.
