The Buen Retiro Park (Parque del Retiro) is an oasis of peace in the heart of Madrid. Just beyond the busy streets, this lush 120-hectare park offers an escape from the hustle and bustle of the city. Created for the Count-Duke of Olivares in the 17th century, the historic park has an elegant ambience with its lovely landscaping and tree-lined paths. From the main entrance at the Plaza de Independencia, visitors arrive at the pool in the center of the park. From here, paths lead to the enchanting Rosaleda (Rose Garden) and the formal French Jardín de Don Cecilio. The Palacio de Cristal(Crystal Palace), a splendid site with its graceful fountain and reflecting pool, often houses art exhibitions. Visitors will find other interesting fountains including Los Galápagos (The Turtles), El Ángel Caído (The Fallen Angel), and La Alcachofa (The Artichoke). A pleasant pastime among locals is sitting at one of the park's open-air cafés, while basking in the sun or relaxing in the shade according to the season. For stargazers, the park has an observatory that was built in 1790.
