2. The Library of Alexandria
Established in the 3rd century BCE, the Library of Alexandria was a monumental center of learning, housing an extensive collection of texts from across the ancient world. Its destruction unfolded over several centuries, with significant events including Julius Caesar’s civil war in 48 BCE, which led to a devastating fire that damaged the library. Later, in 391 CE, the Christian patriarch Theophilus ordered the demolition of the Serapeum, a temple that housed part of the library’s collection. By the time of the Arab conquest in the 7th century CE, the library had ceased to exist, and its vast repository of knowledge was lost to history. (britannica.com)
