It is the road starting form the great theatre to the Celsus Library, which is the portion of the sacred way that leads past Panayirdagi to the Temple of Artemis. The construction of the marble road dates to the 1st century A.D, and it was rebuilt in the 5th century. The western side of the road is enclosed by the agora wall, and on the wall is a higher platform, which was constructed during the reign of Nero. It was built over the wall, for pedestrians.
On the marble road, there are some drawings believed to be an advertisement of the Brothel. This advertisement is known as the first advertisement in history. There is a footprint on the advertisement, one finger showing the library, and other showing the brothel. The known explanation of this sign is that the footprint shows that one should turn at that point; the woman’s head symbolizes the women waiting in the Brothel and the heart shows that the women are eager for love. The busts and statues of the important people were erected along the road, and the letters from emperors were carved into the marble blocks to let people read.
