The Arcadian Gate is a monumental construction, built with large limestone rectangular stones and that is why, it inspires awe to the visitors. It is circular and spacious, with two entrances (a dual internal and external). The internal entrance led to a paved road towards City Market and the external to the road, which ended at the capital of Arcadia, Megalopolis. There are two square protective towers- to the right and left of the external entrance of the Arcadian Gate - communicating with the main construction of the gate, which has circular plan view.
Hermaic columns were erected in the internal circular space of the Arcadian Gate as the god Hermes protected the gates. A cluster of funerary monuments was recently discovered outside the Arcadian Gate and it was used during the 2nd, 3rd and 4th century. A.D. for the burial of the noble families of the city.

These colossal blocks of stone have been around for more than 2000 years, and will probably still be sitting in the same place 2000 years more.
