Unfortunately, the provided reference does not explicitly state which historical site is the most visited in the world. Instead, it lists several of the most visited monuments globally. Based solely on this reference, I cannot definitively answer which site is the most visited. The reference lists several popular historical locations but does not rank them by visitation numbers.
The reference mentions the following most visited monuments in the world:
- Palace of Versailles, Versailles
- Lincoln Memorial, Washington D.C.
- Colosseum, Roman Forum and Palatine Hill Circuit, Rome
- Taj Mahal, Agra
- Parthenon, Athens
- Eiffel Tower, Paris
- Peterhof Palace, St.
- Vietnam Veterans Memorial, Washington D.C.
Because the original question is unanswerable using only the reference text, it is impossible to provide the requested answer.
