This was the city’s market area under Roman rule, and it occupied a much larger area than the current site borders. You can see a lot from outside the fence, but it's worth going in for a closer look at the well-preserved Gate of Athena Archegetis – financed by Julius Caesar in 10 BCE – the propylaeum (entrance gate) to the market, as well as an Ottoman mosque and the ingenious and beautiful Tower of the Winds, on the east side of the site.
