Mercat de Sant Josep de la Boqueria is it's reall name, but the locals uses simply the shortform La Boqueria.
It is a large market with a huge diversity of gods.
It was first heard of in 1277 when the merchants needed a place to sell their meat. in 1470 it was a market which sold pigs. At that time it was not formally known as a market, but was considered an extension of the Placa Nova, which then extended to the Placa del Pi. Later on, the authorities decided to construct a separate market on La Rambla, housin mainly fishmongers and butchers. Not before the late 18th century was it know as an official market. It was not until 1914 the market got a roof of metal. The roof still exist today.
It is well worth an hour or two. Because you have never seen anything like it before. Ever! it contains all kinds of gods, from fish to bread to fruits to sweet in all kinds of shapes and sizes. and the smells, the sight, the people are magnificent! when you have seen it you understand why so many locals never shop their food anywhere else!
