The former market hall Mercat del Born covers archaeological ruins which were part of the La Ribera district that was demolished after the Siege of Barcelona (1713–14) and the defeat of Catalonia in the War of Succession. Another place of interest is the Fossar de les Moreres, the site of a mass grave of Catalan soldiers fallen during the siege of 1714. Part of the quarter of La Ribera was demolished after 1714 to build a military citadel to punish the defeated city.
