Propylaea (Acropolis of Athens)


The Propylaea was the monumental gateway to the Acropolis of Athens, and was one of several public works commissioned by the Athenian leader Pericles in order to rebuild the Acropolis a generation after the conclusion of the Persian Wars. Pericles appointed his friend Phidias as the supervisor and lead architect of this massive project, which Pericles allegedly financed with funds appropriated from the treasury of the Delian League. According to Plutarch, the Propylaea was designed by the architect Mnesikles, about whom nothing else is known. Construction began in 437 BC and was terminated in 432, when the building was still unfinished.
The Propylaea was constructed of white Pentelic marble and gray Eleusinian marble or limestone, which was used only for accents. Structural iron was also used, though William Bell Dinsmoor analyzed the structure and concluded that the iron weakened the building. The structure consists of a central building with two adjoining wings on the west side, one to the north and one to the south.
The core is the central building, which presents a standard six-columned Doric façade both on the west to those entering the Acropolis and on the east to those departing. The columns echo the proportions of the columns of the Parthenon. There is no surviving evidence for sculpture in the pediments.
The central building contains the gate wall, about two-thirds of the way through it. There are five gates in the wall, one for the central passageway, which was not paved and lay along the natural level of the ground, and two on either side at the level of the building's eastern porch, five steps up from the level of the western portico. The central passageway was the culmination of the Sacred Way, which led to the Acropolis from Eleusis.
Entrance into the Acropolis was controlled by the Propylaea. Though it was not built as a fortified structure, it was important that people not ritually clean be denied access to the sanctuary. In addition, runaway slaves and other miscreants could not be permitted into the sanctuary where they could claim the protection of the gods. The state treasury was also kept on the Acropolis, making its security important.
The gate wall and the eastern portion of the building sit at a level five steps above the western portion, and the roof of the central building rose on the same line. The ceiling in the eastern part of the central building was famous in antiquity, having been called by Pausanias "...down to the present day unrivaled." It consisted of marble blocks carved in the shape of ceiling coffers and painted blue with gold stars.

The colonnades

The outer wings to the right and left of the central building stood on the same platform as the western portion of the central building but were much smaller, not only in plan but in scale. Like the central building, the wings use Doric colonnades and entablatures. The central building also has an Ionic colonnade on either side of the central passageway between the western Doric colonnade and the gate wall. This is therefore the first building known to us with Doric and Ionic colonnades visible at the same time. It is also the first monumental building in the classical period to be more complex than a simple rectangle or cylinder.
The western wing on the north was famous in antiquity as the location of paintings of important Greek battles. Pausanias reports their presence, but few scholars believe the room was planned to hold them. Recent scholarship, following the lead of John Travlos, has taken the northern wing to have been a room for ritual dining. The evidence for that is the off-center doorway and the position near the entrance to the Acropolis.
The wing on the south, though much smaller, was clearly designed to make the whole structure appear to be symmetrical. It seems only to have functioned as an access route to the Temple of Athena Nike, which stood to the south and further west, on a raised bastion.

Plans for eastern and western side of Propylaea

There were two wings planned for the eastern side of the Propylaea, facing in toward the Acropolis. Preparations for both wings are apparent at the eastern end of the central building and along the side walls, but it seems that the plan for a southern wing was abandoned early in the construction process since the old fortification wall was not demolished, as required for that wing.
The north wing was not built either. Had it been constructed, it seems that the level of the floor would have been problematic. To the extent that preparations had been made, they were for a floor at the level of the western portion of the building, considerably below the level required on the east.
As a result of the outbreak of the Peloponnesian War between Athens and Sparta in 431 BC, the Propylaea was never completed. Not only are the eastern wings missing, the wall surfaces were not trimmed to their finished shapes, and so-called lifting bosses remain on many blocks.

Later history

The extant monumental marble stairway was built in the Claudian period, circa 52 AD, which replaced the zigzag ramp of Mnesicles, and following the Herulian invasion the Buelé Gate was constructed immediately in front of the Propylaia as a part of the further fortification of the citadel and the city. During the period of the Duchy of Athens, it served as the palace of the Acciaioli family, who ruled the duchy from 1388 to 1458. It was severely damaged by an explosion of a powder magazine in 1656, foreshadowing the even more grievous damage to the Parthenon from a similar cause in 1687. A Frankish tower, erected on the south wing, was pulled down in 1874.

Restoration

Today the Propylaea has been partly restored, since 1984 under the direction of Tasos Tanoulas, and serves as the main entrance to the Acropolis for the many thousands of tourists who visit the area every year. In the period before the 2004 Olympic Games in Athens, the Propylaea was shrouded in scaffolding as restoration work was undertaken. At the end of 2009 all scaffolding was removed, and the building is now open fully to view again. The famous ceilings have even been partly restored.
The restoration of the central building of the Propylaea was awarded a European Union Prize for Cultural Heritage / Europa Nostra Award in 2013.
