Lion Gate is the popular modern name for the main entrance of the Bronze Age citadel of Mycenae in southern Greece. It was erected during the thirteenth century BC, around 1250 BC, in the northwestern side of the acropolis. In modern times, it was named after the relief sculpture of two lionesses in a heraldic pose that stands above the entrance.

Mycenae is an archaeological site near Mykines in Argolis, north-eastern Peloponnese, Greece. It is located about 120 kilometres south-west of Athens; 11 kilometres north of Argos; and 48 kilometres south of Corinth. The site is 19 kilometres inland from the Saronic Gulf and built upon a hill rising 900 feet above sea level.
