The monumental gate, situated next to the theater, led in Roman times to the center of Side. Even today, traffic to the historical part of the town passes this gate. An elegant building, adjacent to this gate and supported by the ramparts of the 4th century AD, was probably erected in honor of Emperor Vespasian.

The current height of the monumental gate is 13.5 meters, but in the ancient times the structure was much higher. The entablature above the gate once supported the statue representing, most probably, a quadriga or a two-wheeled wagon drawn by four horses.

The Byzantine cistern known as Tekir Ambarı is one of the less-known historical attractions of Silifke. Its currently used name literally means "tabby warehouse." Although finding the cistern is a challenge in itself, the structure has impressive dimensions, and its exploration is highly recommended for history-conscious travelers.

In the reign of the Seljuk Turks caravans carrying goods from the Far East roamed through the area of Anatolia. In order to facilitate the trade and support the merchants in their hard work a dense network of caravanserais (inns for travelers) was then established in Asia Minor. The last stop before the port of Antalya was Kırkgöz Han caravanserai, situated in Döşemealtı district which is today the metropolitan area of Antalya. This magnificent building has been recently renovated with the aim of hosting various events and festivities, so if you fancy a wedding, a conference or a training event in an unusual place, then you might consider this location. The name of this caravanserai - Kırkgöz - literally means "Forty Eyes" and is derived from the old name of Döşemealtı district, which is known for its many water sources.
