Megastructure Family Challenge

We've had a fabulous morning designing and building our own 'Megastructures'. We had 100% attendance today which is great and it was so nice to see so many family members supporting the event. Everyone worked together to build 7 Megastructures in total. We had: Big Ben, The Eiffel Tower, Minar-e-Pakistan, Tower Bridge, Burj Khalifa, Empire State Building and the Tower of Pisa.

Can you remember where in the world you would find these buildings?
