way into the acropolis
. It serves as an excellent representation of the post and lintel
architectural structure typical of Mycenaean civilization
(1600 BCE to 1100 BCE).
The post and lintel structure is built into the wall surrounding it and capped with a corbeled (triangular shaped) arch in which the lion figures stand in relief. The lions were symbolic of the earth which they protected inside of the city.
An excellent photograph of the gate that gives a good sense of its size can be found here:
