The Palacio de Cristal is a glass pavilion located in Madrid's Retiro Park. It was built in 1887 to house exotic plants from the Philippines for an exhibition, but now serves as a venue for contemporary art exhibitions and events.

The building was designed by Spanish architect Ricardo Velázquez Bosco, and it is named for its iron structure and glass walls, which make it look like a crystal palace. The pavilion is set on a small lake in the park, adding to its beauty and making it a popular spot for tourists and locals alike.

Inside, the Palacio de Cristal has a large central hall with a glass ceiling and walls, surrounded by galleries that are used for exhibitions. The natural light that streams in through the glass walls gives the space a magical, ethereal feel.

The Palacio de Cristal has hosted many important art exhibitions over the years, including shows by famous artists like Joan Miró, Yoko Ono, and Anish Kapoor. It also serves as a venue for other cultural events, such as music concerts and dance performances.
