Once a fortress designed to consolidate Madrid's military occupation of Barcelona, the Ciutadella is now the city's main downtown park. The clearing dates from shortly after the War of the Spanish Succession in the early 18th century, when Felipe V demolished some 1,000 houses in what was then the Barri de la Ribera to build a fortress and barracks for his soldiers and a glacis, or open space, between rebellious Barcelona and his artillery positions. The fortress walls were pulled down in 1868 and replaced by gardens laid out by Josep Fontseré. In 1888 the park was the site of the Universal Exposition that put Barcelona on the map as a truly European city; today it is home to the Castell dels Tres Dragons, built by architect Lluís Domènech i Montaner as the café and restaurant for the exposition (the only building to survive that project, now a botanical research center), the Catalan parliament, and the city zoo.
