Indeed, so many great opportunities:
Taj Mahal, Cahokia, Easter Island (Moai), Lascaux Caves, Tikal,...
Even though only the Pharos was a secular monument when you consider the original 7 Ancient Wonders, I doubt we'll ever see a set focused on sites still deemed sacred in modern times (Mecca, Jerusalem, Vatican, Bodhi Tree, Graceland, Fenwey Park, North Pole, Area 51, etc).
Sorry, my mind wandered... The 7 Wanders
