It's been traditionally the fishermen district of Barcelona and it still displays a peculiar flavour.
The Old Harbour ("el Port Vell") is flanked by a promenade actually known as "Passeig de Joan de Borbó" (after the King's father who held the title of Count of Barcelona" ) spotted with typical fish restaurants. A true paradise for skaters and cycle-tourist.
On its eastern side one can still see the old light house dating from the XVIIth century and later converted into a clock tower.
On the opposite side, at the start of the promenade, it still stands one of the old warehouses , now the site of Catalonia's History Museum.
The triangle is closed by the beach ("la platja de la Barceloneta") one of the most popular either for locals and tourists.
