Like masked warriors getting ready for battle, they stand sentinel waiting for their next order. Guarding their charges with their lives, they spew hot air at enemies that approach. Wait… What?

“They” are actually chimneys on the rooftop of Casa Milà, an apartment building in downtown Barcelona, Spain. Born out of the imagination of Antoni Gaudí – the master of Catalan Modernism – these chimneys would not look out of place in a museum.
