The Alcázar of Madrid was a royal palace located in the heart of Madrid, Spain. Originally built in the 9th century as a fortress, it was later transformed into a grand palace. The structure was known for its impressive architecture and beautiful gardens, making it a significant symbol of Spanish history. In 1734, the Alcázar was destroyed by a fire, leading to the construction of the current Royal Palace of Madrid on the same site. Today, the Royal Palace serves as the official residence of the Spanish royal family and is open to the public for tours, showcasing its rich history and art collections.
