Plaça d'Espanya (Catalan pronunciation: [ˈplasə ðəsˈpaɲə]; English: Plaza of Spain) is one of Barcelona's most important squares, built on the occasion of the 1929 Barcelona International Exposition, held at the foot of Montjuïc, in the Sants-Montjuïc district.
The buildings were designed by Nicolau Maria Rubió i Tudurí.
The square was built on a site that had been previously used for public hangings, until the creation of the now demolished Ciutadella fortress in 1715, where the gallows were moved.
It was designed in 1915 and built in 1929 so that it could be ready to host the 1929 Universal Exposition.
Plaça d'Espanya is also a major transport hub that serves most parts of the Metropolitan Area of Barcelona.
