What if belief in extraterrestrials had not only inspired science fiction, but also shaped our cities, our beliefs, and our works of art? Forgotten UFO-ports, mystical temples, intergalactic domes, visionary sculptures… This book explores a fascinating world where cosmic imagination becomes earthly reality. From the Andes to Piedmont, from California to Brazil, Philippe Baudouin investigates these places inhabited by the expectation of an Other coming from the stars. A spectacular, highly documented, and richly illustrated journey.
