How many years did it take to build the city of troy?

The construction of the city of Troy, particularly the well-known Troy VI and Troy VII layers, spanned several centuries rather than a specific number of years. Archaeological evidence suggests that the city was continuously inhabited and rebuilt over time, with significant construction phases occurring from around 3000 BCE to 1000 BCE. The legendary Trojan War, as depicted in Homer's epics, is believed to have taken place around the 12th century BCE, but the actual timeline of its construction is more complex and gradual.
