Royal libraries are collections of books and manuscripts that belong to a monarchy or royal family. These libraries often contain rare and valuable texts, reflecting the culture, history, and knowledge of the time. They serve as important centers for learning and preservation of literature, art, and science. Throughout history, many famous royal libraries have existed, such as the Library of Alexandria in ancient Egypt and the Royal Library of Ashurbanipal in ancient Assyria. Today, some royal libraries are open to the public, allowing people to explore their rich collections and learn about the heritage of the monarchy.
