Greece
Ancient Greece was a collation of city states. Each city state had a different government structure, laws, and cultural traditions. The two most famous states are Athens and Sparta. Athens was a democracy that was rich in trade, while Sparta was a monarchy and a military power. Athens created many of the famous structures we know today, such as the Parthanon, The two city's rivalry would spark a number of wars, with Sparta finally conquering Athens in 40 B.C. This victory was short lived however as a few decades later all of Greece was conquered by Philip II of Macedon, the father of Alexander the Great.
The Parthenon is the most famous structure of ancient Greece. Built by the Athenian Politian/General Themistocles in 438 B.C., it was designed as a temple to the Greek goddess Athena. The building is 228 by 101 feet, and over 40 feet tall. The top of the structure was adorned with statues and engravings. Inside was a gold statue of Athena, which cost as much if not more than the Parthenon it's self. The building of the Parthenon and its statue almost bankrupted Athens, and was actually disliked by most Athenians.
