The gate is located at what is
considered to be the beginning of Curetes Street. As you can see
each of the pillars have a two-storied edifice with the lower
storey being a wide arched passageway. In the upper story, there
are six columns in a row. Reliefs of flying Nikes that are found
today in Domitian Square used to be situated at the corners
where the arch joins the pillars with Corinthian capitals. One
of these reliefs and most of the construction fragments have not
yet been found. Hopefully some day they will and can be added to
the gate.The two centrally
located columns at the upper level resemble the lintels of the
gate. On these two columns, there are two reliefs of Heracles
depicted wrapped in a Nemea lion skin. They are like the
caryatids supporting Corinthian capitals and exhibit 2nd century
craftsmanship. They were moved here in the 5th century from
another location.
The Heracles Gate narrowed the
access to the street, preventing the passage of vehicles.
Therefore, from the Fourth Century onward, the street become a
pedestrian area.
