The Great Lion Gate of the Fortress of Agammemnon

This ancient Mycenaean fortress is believed to be the one from which Agammemnon left for Troy. The relieving triangle above the lintel was a feature of this particular style of Bronze Age architecture.
The massive stone walls of this c. 1450 B. C. fortress show clearly in this view. Later fortifications often used smaller stones as fill between outer facings of large masonry blocks.
