Known as the Burj Doha or Doha Tower, this building is another unique architectural piece by Jean Nouvel. From first glance, it may look like a glorified silo-like building. However, the outsides of he tower is covered in intricate designs just like the dome of the Louvre in Abu Dhabi. You can see that Nouvel strives to keep some of his unique fingerprints in different buildings. This building is in Doha and it cost about $125 million to make and it is said to be a cousin of the Burj Khalifa, the tallest tower in the world.
