An enormous cathedral that is currently being built in the Spanish city of Barcelona.
This is a must see piece of architecture that is a combination of modern and older Cathedral style work. It truly is awe inspiring, and features multiple towers that strech towards the sky. You can take an elevator to the top from the main tower and have a grand view of Barcelona. The building has a fascinating history, having been under construction for over 50 years and is only scheduled to be completed sometime after 2020.
