Based on available data, the Eiffel Tower is arguably the most visited wonder of the world.
While pinpointing the "most visited" is challenging due to varying data collection methods and definitions of "wonder," the Eiffel Tower consistently ranks high in visitor numbers compared to other iconic landmarks considered "wonders." The Colosseum, Venice, La Sagrada Familia, and the Empire State Building also attract millions annually and are frequently cited among the most visited.
It's important to note:
- Definition of "Wonder": What constitutes a "wonder of the world" is subjective. Lists vary (e.g., Seven Wonders of the Ancient World, New7Wonders of the World, etc.) and have different criteria.
- Data Availability: Accurate and consistent visitor data across all potential "wonders" globally is difficult to obtain.
- Defining "Visited": This can encompass ticketed entry, simply viewing from the exterior, or passing through a location.
Despite these limitations, the Eiffel Tower stands out due to its consistently high visitor count and recognizability.
