The Acropolis of Athens is an ancient citadel located on a high rocky outcrop above the city of Athens and containing the remains of several ancient buildings of great architectural and historic significance, the most famous being the Parthenon.

The Temple of Athena Polias was constructed on the Acropolis Hill around 570 - 550 B.C. This Doric style limestone shrine of the Protectress of the city was named as Hekatompedon, meaning 'the one with hundred feet', and probably stood right where the Parthenon stands today.

Numerous other temples were erected on the Acropolis in the so-called archaic period, but many of them were either completely or partially destroyed during the Persian invasions. The so-called Persian rubble is the most affluent archaeological deposit ever unearthed on the Acropolis.

Apart from the three main structures, the Theater of Dionysus is a significant monument built at the foot of the Acropolis. It is an open-air theater, and probably the first of its kind in Athens.

Another impressive structure is the Stoa of Eumenes, which is a covered colonnade to be used as a walkway by the people.

The Odeon of Pericles, which is just beside the theater of Dionysus, is an interesting structure. This square structure was constructed in 435 B.C. by Pericles, and was meant for holding musical concerts. The original structure was burnt down in 1st century B.C., and was later on reconstructed in 2nd century A.D.

Other structures of the Acropolis include the Sanctuary of Artemis Brauronia, Altar of Athena, the Sanctuary of Zeus Polieus, the Asclepeion, the Eleusinion, and so on.

The Parthenon is a temple on the Athenian Acropolis, Greece, dedicated to the goddess Athena, whom the people of Athens considered their patron.

The Parthenon measurement is 111 feet by 228 feet, or 30.9 meters by 69.5 meters.

Its construction began in 447 BC when the Athenian Empire was at the height of its power. It was completed in 438 BC, although decoration of the building continued until 432 BC.

After the Ottoman conquest, it was turned into a mosque in the early 1460s. On 26 September 1687, an Ottoman ammunition dump inside the building was ignited by Venetian bombardment. The resulting explosion severely damaged the Parthenon and its sculptures.

The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped amphitheater with a three-story stone front wall and a wooden roof made of expensive, cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and turned into a ruin by the Heruli in 267 AD.
