The Palacio Real de Madrid, known as the Royal Palace of Madrid, stands as a significant cultural and historical monument in Spain. It is renowned for being the largest royal palace in Western Europe, with an impressive 135,000 square meters of floor space and 3,418 rooms. Although it is the official residence of the Spanish royal family, it is used primarily for state ceremonies, with the royal family choosing to reside in the more modest Palace of Zarzuela. The palace's majestic architecture and rich interiors, which include works of art and historical artifacts, attract almost 2 million visitors annually.
