In the central area, it also houses "Maremagnum" (a shopping mall and nightlife complex), a multiplex cinema, the IMAX Port Vell (large-format cinema complex), and Europe's largest aquarium, containing 8,000 fish and 11 sharks in 22 basins filled with 6 million litres of sea water. Because it is located in a designated tourist zone, the Maremagnum is the only commercial mall in the city that can open on Sundays and public holidays. Next to the Maremagnum area are the "Golondrines", small ships that take tourists for a visit around the port area and beyond.
