Shaped like an upturned ship (others say it resembles a UFO landed in the middle of the city), the Atlantic Pavilion (now branded "Altice Arena") is officially Portugal's largest indoor arena, with a capacity for over 15,000 spectators.
It is the venue for major visiting bands and artists, and has hosted international events such as the Tennis Masters championships, the World Indoor Athletics Championship, the MTV Europe Music Awards and the Web Summit.
A short walk from there is the Garcia da Orta Garden, named after a 16th-century Portuguese doctor who studied and classified Asian plants. Its vegetation came from the regions of the world explored by the Portuguese during the Age of Discovery.
