"The Portugal Pavilion is a striking building designed by Portugal's Pritzker Award-winning architect Alvaro Siza Vieira. It's remarkable sagging concrete roof weighing 1,400 tonnes and measuring 50 by 67 meters (167 by 223 ft) is an instant attention-grabber, undulating like a sailcloth, keeping the maritime theme of most of the district's architecture."
