Gaudi is a celebrated architect, and he designed many interesting buildings in Barcelona. Here is a sample of his work.
Perhaps most famous of all his work, though, is Sagrada Familia, which has been under construction for 125 years and is expected to remain under construction for another 20 years. The level of detail involved here is amazing.
It is also incredibly large, especially compared to the other buildings in Barcelona. And the biggest towers haven't even been erected, yet.
