The Retiro Park (Spanish: Parque del Buen Retiro, literally "Good Retreat Park"), also known as Buen Retiro Park or simply El Retiro, is one of the largest city parks in Madrid, Spain. The park belonged to the Spanish monarchy until 1868, when it became a public park following the Glorious Revolution. The park is located at the edge of the city centre, near both the Alcalá Gate and the Museo del Prado, and covers 1.4 km2 (350 acres). It has gardens, monuments, galleries, an artificial lake, and event-hosting venues.
