Constructed and established in the 3rd century BC, The Royal Library of Alexandria located in Alexandria, Egypt was one of the largest and most significant libraries of the ancient world. It was dedicated to the nine goddesses of the arts known as the Muses.
Throughout the patronage of the Ptolemaic dynasty the ancient library flourished and became a major center of scholarship and included many collections of works, lecture halls, meeting rooms and gardens it was also part of a larger research facility called the Musaeum of Alexandria, here many of the most famous thinkers of the ancient world studied.
Sadly the library is arguably most famous for having been burned down, this resulted in the mass loss of ancient texts including many scrolls and books. It is not known what exactly was kept in the library but it is thought that we as humans lost a significant amount of ancient knowledge as a result.
