This probably tells you a lot about me but I went for:
Acropolis – Old figure of civilisation
Easter island figures – mysterious people alone on a island
Great wall – Huge effort to build the structure
Hagia Sophia – An impressive temple now museum
Neuschwanstien Castle – A real fantasy castle
Stonehenge – Ancient, mysterious, amazing.
Taj Mahal – An impressive statement.
Choose wisely!
