The pottery phases on which the relative dating scheme is based (EH, MH, LH, etc.) do not allow very precise dating, even augmented by the few existing C-14 dates due to the tolerance inherent in these. The sequence of further construction at Mycenae is approximately as follows. In the middle of LHIIIB, around 1250 BC or so, the Cyclopean wall was extended on the west slope to include Grave Circle A. The main entrance through the circuit wall was made grand by the best known feature of Mycenae, the Lion Gate, through which passed a stepped ramp leading past circle A and up to the palace. The Lion Gate was constructed in the form of a "Relieving Triangle" in order to support the weight of the stones. An undecorated postern gate also was constructed through the north wall.
