items were made from amber imported from the Baltic region, carnelian imported from India, and lapis imported from Afghanistan. Some of these items are strikingly similar to those found at sites such as Poliochni and Ur, leading some scholars to speculate that they may have been made by itenerant jewlers who worked routes covering much of the Ancient Near East. Troy II was destroyed twice. After the first destruction, the citadel was rebuilt with a dense cluster of small houses on an irregular plan. The final destruction took place around 2300 BC. While some scholars have linked this destruction to a broader crisis that affected other Near Eastern sites, there is no definitive evidence for the city having been destroyed by an attack. Troy II is notable for having been misidentified as Homeric Troy, during initial excavations, because of its massive architecture, treasure hoards, and catastrophic destruction. In particular Schliemann saw Homer's description of Troy's Scaean Gate reflected in Troy II's imposing western gate. However, later excavations demonstrated that the site was a thousand years too old to have coexisted with Mycenaean Greeks. Troy III–V Troy continued to be occupied between 2300 BC and 1750 BC. However, little is known about these several layers due to Schliemann's careless excavation practices. In order to fully excavate the citadel of Troy II, he destroyed most remains from this period without first documenting them. These settlements appear to have been smaller and poorer than previous ones, though this interpretation could be merely the result of gaps in the surviving evidence. The settlements included a dense residential neighborhood in the citadel. Walls from Troy II may have been reused as part of Troy III. By the period of Troy V, the city had once again expanded outside the citadel to the west. Troy IV sees the introduction of domed ovens. In Troy V, artifacts include Anatolian-style "red-cross bowls" as well as imported Minoan objects. Troy VI–VII Troy VI–VII was a major Late Bronze Age city consisting of a steep fortified citadel and a sprawling lower town below it. It was a thriving coastal city with a considerable population, equal in size to second-tier Hittite settlements. It had a distinct Northwest Anatolian culture and extensive foreign contacts, including with Mycenaean Greece, and its position at the mouth of the Dardanelles has been argued to have given it the function of regional capital, its status protected
