It is an amazing building, just the kind of architecture I love, modern, striking, strange, or as you say, alien hahaha, wow it does look like an alien spaceship. You have good pictures here hwrmano, thank you very much for sharing with us your passion for architecture and good taste...
Thanks a lot for your sincere admiration @jesuslnrs! And yes, this landmark is certainly beautiful despite its peculiar architecture. Sometimes, being radical helps in capturing valuable attention especially if it's free public marketing used by famous institutions of national importance. Have an enjoyable week! ☺️
