Part of my choices isnt due to the largest or the oldest but by our monuments that have such an impact and become such apart of the countries they are within making them a wonder in there own right.
- Hagia Sophia (Full credit of it to Byzantium, not Turkey)
- The Acropolis
- Paris Opera House
- Windsor Castle (It just has that special something)
- Neuschwanstein Castle
- Big Ben
- Eifel Tower
