I have this book '1001 building you must see before you die' and i thought why don't i do that? 1001 is way too many but i can do 101 with some schematics from other people, if you would like to help please comment and then i will add your structures to the collection and your name will be added to the list of creators. I already have some ideas on what to build:

1. Great Pyramid of Giza
   
2. Temple of Hatshepsut
   
3. Pantheon
   
4. Church of Santa Costanza
   
5. Qui Nhon Ban it Towers
   
6. Big Wild goose pagoda
   
7. Mosque of Masjid-i-jami
   
8. Basilica of St. Sernin
   
9. Castel de Monte
   
10. Lincoln Cathedral
    
11. Temple of the Golden Pavilion
    

These are all grand buildings and will take time to do :P but please if u want to suggest something or have one already built dont hesitate to tell me :)
