6The Library of Alexandria, Egypt

One of the most famous libraries in ancient history, the Library of Alexandria was a center of learning and culture in the Hellenistic world. Founded in the 3rd century BCE, it housed thousands of scrolls and texts, making it a hub for scholars from around the Mediterranean. The library suffered several attacks over centuries, with the final destruction often attributed to a series of wars and fires. The exact cause of its demise is still debated, but the loss of such a vast repository of knowledge remains a tragic consequence of conflict.
