Trevi Fountain in Rome implemented a €2/person charge and I think it’s the right approach but I am sure I will be burned at the stake for this unpopular opinion.

Trevi Fountain Implements €2 Fee
From February 1st, 2026 Rome will implement a €2 per person fee for up close viewing of the famed fountain. The goal is to reduce crowds with a nominal charge and improve the experience for tourists.
The cost is nominal. Even for budget travelers, €2, while not as accessible as free, is still very inexpensive. Some sites are prohibitively expensive, the Eiffel Tower charges €36 to ride all the way to the top, but even €11 just to walk the stairs to the second level.
I’d gladly pay €2 for the perfect shot and a little moment in time with the fountain and my family.
