Built between 437 BC and 432 BC, the Propylaea is the grand gateway to the Acropolis of Athens. It features six towering columns made of marble and limestone. It is an impressive and striking staircase that leads to the top of the Acropolis. Comprising two porticos on the east and west along with a central doorway in the front, the Propylaea is an architectural marvel with intricate details that add to the grandeur of the Acropolis.

One of the most popular sites at the Acropolis, the Parthenon was originally built as a temple dedicated to the Greek Goddess Athena Parthenos. An example of Doric architecture, the Parthenon features elaborate sculptures, mosaics, and ionic columns made of marble. It first served as a cathedral and was then converted into a mosque. The structure has undergone several restoration projects over the years with the aim to preserve this important symbol of Greek history.

One of the oldest architectural complexes on the southern slope of the Acropolis, the Theatre of Dionysus was built in the fourth century BC and is dedicated to Dionysus, the Greek God of wine and good times. The Greek tragedies of Euripides and Sophocles were performed at this sprawling theatre, which could accommodate almost 20,000 people, making it the largest public space in the ancient city of Athens.

Constructed between 426 BC and 421 BC, the Temple of Athena Nike was the first ionic temple built at the Acropolis. Located right next to the Propylaea, the temple was built in honor of Greek goddesses Athena and Nike, the protectors of Athens. However, the Turks demolished it in 1686. The temple has, since then, undergone quite a few restorations. It was rebuilt in 1834 only to be pulled down and reconstructed again in 1998.

The Erechtheion was named after Erechtheus, the mythical king. It was built between 421 BC and 406 BC and shares ground with the Old Temple of Athena and Pandroseion. Do not miss the Caryatids – six female statues that support the roof of the temple. Located on the northern side of the Acropolis, the Erechtheion is believed to be the mastermind of architect Mnesicles and is a must-see.

The Odeon of Herodes Atticus was built in 162 AD as a theatre that could accommodate about 5,000 people. Located on the southwest slope of the Acropolis, this theatre was built by politician Herodes Atticus in memory of his wife Aspasia Annia Regilla. This massive structure is made entirely of stone and is still used as a venue for concerts and cultural events in Athens.
