Ancient Castles
Babylon - Most of what we know comes to us from ancient writings. For example it is believed that the ancient wall for Babylon was around 23 feet thick, strengthened at intervals by towers and there was also a moat. Because the countryside was relatively flat, castles on hills were a rare sight.
Mycenae - The Acropolis stands on a hill at the north end of the low acidity. There is a strong wall of massive masonry. It is entered from the low city by a ramp and a double gateway.
Troy - There are remains from nine cities each one buried beneath the other. The earliest are believed to date from 3000 BC to 2560 B.C. The sixth city which was discovered by Dorpfeld in 1893 AD is probably the city of homeric fame.
