Europe's largest land-based digital screen welcomes visitors to the new Barcelona Aquarium. The images show the sea lapping into the Port Vell building before two impressive life-size sperm whales emerge. A clear statement of intent about what awaits visitors to a marine center that has been completely renovated now that it's 30 years old and, taking advantage of new technologies, offers an even more immersive experience, allowing visitors to admire the ocean in all its depths and be aware of its fragility.
