Nestled in Madrid’s lush Buen Retiro Park, the Palacio de Cristal is a stunning 19th-century glass pavilion inspired by London’s Crystal Palace. Built in 1887 to house exotic plants, its iron and glass structure reflects a harmonious blend of architecture and nature. Today, it serves as an exhibition space for contemporary art, with installations transforming the interior while the serene reflecting pond enhances its timeless elegance. Visitors often linger nearby at the nearby Fuente de Neptuno or stroll through the rose garden, making it a cultural gem within one of the city’s most beloved green spaces.
