This was taken at the Lisbon Oceanarium. It is the the largest indoor aquarium in Europe with over a million visitors every year. Located at the Parque das Nações and designed by architect Pedro Campos Costa this building is a new addition to the existing Lisbon Oceanarium. The tiles are in seven, subtle shades of white, and were provided by Toni Cumella, a ceramicist, who has a workshop called Ceràmica Cumella in Barcelona. it is definitely worth a whole day to go and exploreit and the nearby areas.
