A commercial marketplace was donated to Athens by Julius Caesar in the 1st century B.C. A street lined with columns connected the new marketplace, where all commercial activities were gravitated, with the Ancient Agora. It had a central courtyard surrounded by columns with stores right behind them. Next to it are to be seen the roman latrines.
By the Roman Forum stands the Tower of the Winds, a tower – like structure built at about the same time. It is one of the most peculiar buildings of ancient times, which served as a public sundial, weathervane and waterclock.
