In ancient Greek chronology, the sack of Troy was dated to 1184 BC. By the nineteenth century, there was widespread scholarly skepticism that the Trojan War had ever happened and that Troy had even existed, but in 1873 Heinrich Schliemann announced to the world that he had discovered the ruins of Homer's Troy at Hissarlik in modern Turkey. Some contemporary scholars think the destruction of Troy VIIa "circa" 1220 BC was the origin of the myth of the Trojan War, others that the poem was inspired by multiple similar sieges that took place over the centuries.
