Later, the authorities decided to construct a separate market on La Rambla, housing mainly fishmongers and butchers. It was not until 1826 that the market was legally recognized, and a convention held in 1835 decided to build an official structure. Construction began on March 19, 1840 under the direction of the architect Mas Vilà. The market officially opened in the same year, but the plans for the building were modified many times. The inauguration of the structure finally took place in 1853. A new fish market opened in 1911, and the metal roof that still exists today was constructed in 1914.
