The Diada Nacional de Catalunya is commemorated every 11 September, marking the fall of Barcelona in 1714 during the War of the Spanish Succession. Over time, this episode became a symbol of resistance, identity and political expression. In Barcelona and throughout Catalonia, the day is marked by floral tributes, demonstrations, institutional events and expressions of popular culture in streets and squares. Beyond its historical significance, La Diada brings together memory and the present, becoming an opportunity to reaffirm Catalan culture, its rights and its aspirations for the future.

Places such as the Palau de la Generalitat, the Parlament de Catalunya, the Palau Güell and several museums mark the Diada with open days.
