Castell de Montjuïc
Built in 1640 by rebels against Felipe IV, the castle has had a dark history as a symbol of Barcelona's military domination by foreign powers, usually the Spanish army. The fortress was stormed several times, most famously in 1705 by Lord Peterborough for Archduke Carlos of Austria. In 1808, during the Peninsular War (War of Spanish Independence), it was occupied by Napoléon's troops. During an 1842 civil disturbance, Barcelona was bombed from its heights by a Spanish artillery battery. After the 1936–39 civil war, the castle was used as a dungeon for political prisoners. Lluís Companys, president of the Catalan government during the civil war, was executed by firing squad here on October 15, 1940. In 2007, the fortress was formally ceded back to Barcelona.
An excellent visitor center highlights the history of the castle throughout the ages; other spaces are given over to temporary exhibits. The various terraces offer fantastic panoramic views over the city and out to sea, while the gardens inside the moat host the popular summer Sala Montjuic Open Air Cinema ( www.salamontjuic.org), screening original versions of classic films with live music before the showings.
