Propylaea
The Propylaea were built mainly with Pentelic marble and divided into three sections, the central one and two Doric wings.
Modern and Contemporary era (1821 - )
The first restorations were made in the early 20th century by Nikolaos Balanos.

During the early Christian period (4th-7th century AD) a Christian church was located in the south wing. Similarly, the central portion was used as a church in the 10th century AD. During the Frankish Rule (13th-14th c.) it became the residence of the Frankish ruler.

What I can see
The Αcropolis has two entrances: the Beulé Gate (named after the archaeologist who discovered it), which is part of the late roman fortification (3rd century AD). Upon entering the Acropolis, one can see the Propylaea, which in some parts remained incomplete due to the Peloponnesian War. They were built mainly with Pentelic marble and divided into three sections, the central one and two Doric wings. Between the six Doric columns of the central section, there were five doors built on a transverse wall; only the middle one is still in use. In the north wing there is the “Gallery,” a dining room decorated with paintings, which was used for distinguished guests. The south wing led to the temple of Athena Nike, which was why there was no special gallery room on the south side. The Propylaea and the Parthenon are two buildings that are connected. Although they do not have the same axis, they have the same orientation and very similar ratio.
What I can't see
A Mycenaean period gate existed where architect Mnesicles’ excellent work is currently exhibited. The Propylaea of the archaic period however, was completely destroyed by the Persians. The Propylaea of classical times have a slight difference in orientation compared to the pre existing Propylaea. The architect probably wanted the entrant to be able to see the statue of Athena Promachos and the temples on both sides, that is, the Parthenon and the Erechtheion. Another possible explanation is that with the new orientation, the Propylaea look directly to Salamis. Thus, the historic victory of Athens against the Persians, which determined the course of the later history of the western world, is forever remembered. It suffered many disasters over the centuries, and many additions were removed after Greek independence.
