1. Palacio De Cristal, located in the Buen Retiro Park in Madrid, is a stunning glass pavilion built in the late 19th century. It was originally built to house exotic plant species from the Philippines, but now serves as a space for contemporary art exhibitions and cultural events. The pavilion’s design, by architect Ricardo Velázquez Bosco, was inspired by the Crystal Palace in London. The transparent structure creates a beautiful play of light and shadow, and the surrounding park provides a peaceful atmosphere for visitors to enjoy.
