A must see with a dubious story attached. Wikipedia has "In 41 BC, Mark Antony during his struggle against Octavian, allied himself with Cleopatra VII in Tarsus. [...] Cleopatra entered Tarsus via the port gate. The history of the gate after Cleopatra is not documented, but by analyzing the building stones and the cement, it is usually believed that the original gate was rebuilt during the Middle Ages, either by the Byzantine Empire or by the Abbasids. The popular name of the gate was Kancık Kapı (feminine gate) during the late Ottoman period. However, from the early 20th century, the name Cleopatra kapısı ("Cleopatra's Gate") replaced the former name.

The outer height of the gate is 8.53 metres (28.0 ft) and the inner height is 6.17 metres (20.2 ft). The length of the passage is 6.48 metres (21.3 ft) The mortar used in the original gate was khorosan mortar. The gate was used on the street up to 30 years ago, when it was put under restoration, which resulted in the partial loss of its original appearance."
