The classical Erechtheion is the last in a series of buildings approximately on the mid-north site of the
Acropolis of Athens, the earliest of which dates back to the late
Bronze Age Mycenaean period. L.B. Holland conjectured that the remains under the Erechtheion was the forecourt of a palace complex similar to that of Mycenae. The scant evidence of the period
LHI includes potsherds and scraps of a wall under the foundations of the Ionic temple. From the remainder of the
shaft-grave period, there is nothing from LHII–LH IIIA, only from LH IIIB is there evidence of habitation in the form of terracing, children's graves, and a limestone column base. Hurwitt, arguing by analogy with population centres elsewhere from the period, maintains that there may have been a cult centre on the
acropolis to the armed goddess
a-ta-na-po-ti-ni-ja, which could represent the primitive origins of the Athenian cult. Additionally, the Mycenaean well and
Cyclopean walls, which appear to have been in use between LH IIIB and LH IIIC, attests to attempts to fortify the hill-top as the "strong-built house of Erechtheus" recorded in the Homeric tradition. The well may be an indication of the location of the cult of Erechtheus. The archaeology under the Erechtheion is also poorly evidenced for the archaic and early classical periods. Despite this a number of proposals have been made for a structure on the site immediately before the
Achaemenid destruction of Athens in 480 BCE. Orlandos reconstructs an obliquely orientated
hexastyle amphiprostyle temple, which would have contained the "trident marks" in its pronaos. Others restore a number of
temene adjacent to the
Temple of Athena Polias or a
tetrastyle naiskos. To the south of the Erechtheion site would have been the Dörpfeld Foundations Temple, now thought to be the archaic Temple of Athena Polias, the foundations of which are visible on the acropolis today. Examination of the remains of the north edge of this temple by Korres might suggest the boundaries of the pre-Ionic Erechtheion site and therefore determine the shape of the classical
temenos. Korres argues that a columnar monument marking the kekropeion would have been approximately where the Porch of the Maidens is, and that there was a
stoa for the
Pandroseion adjacent. The building accounts for the classical Erechtheion from 409–404 BC have survived, allowing an unusually secure dating of the construction of the temple. Nevertheless, the question remains of when the building project was inaugurated. There is no primary evidence for when construction began; it is conjectured to be either the 430s or in 421 during the
Peace of Nikias. The latter is broadly the consensus view, the rationale being that this lull in the long
Peloponnesian War would have been the most convenient time to begin a major construction project and that there was a likely hiatus in building during the
Sicilian disaster of 413. Alternatively, dates as early as the mid-430s and as late as 412 have been put forward. Work seems to have ended in 406–405, and the last accounts were from 405–404, though some
mouldings were never finished and some of the bosses of some stone blocks were not chiselled off. The names of the architect-overseers (
episkopos), Philokles and Archilochos, have come down to us. They worked on the site after 409. But the identity of the architect (
architecton) is unknown. Several candidates have been suggested; namely,
Mnesikles,
Kallikrates, and
Iktinos. The subsequent history of the building has been one of damage, restoration and change of use, which complicates the task of reconstructing the original structure. The first recorded fire that the classical building suffered was perhaps 377–376, a second more severe fire took hold sometime in 1st century BCE or earlier followed by a campaign of repair. The Erechtheion along with the
Parthenon suffered a further major destruction at some point in the 3rd or 4th century CE; whether this was due to
Herulian or
Visigoth attack or a natural disaster is unclear.
Julian the Apostate undertook the reconstruction of the Parthenon as a pagan temple in circa 361 and 363, at which point the Parthenon was the only attested site of the cult of Athena on the Acropolis, implying that the Erechtheion had been abandoned. In the post-classical period, the Erechtheion was subject to a number of structural changes that must be assumed to have been prompted by the building's adaptation to Christian worship. The first was its conversion to a pillared hall with a
groin vaulted roof at some point in the 4th century. In the late 6th or 7th century, the Erechtheion was converted into a three-aisled
basilica church with the West Corridor serving as the
narthex. The central portion of the east foundations was removed to make room for a curved
apse. In the 12th century, the basilica was renovated. The round apse was enlarged and was given straight sides on the exterior. The chancel screen was extended to the North and South Walls. During the
Frankish occupation (1204–1458), the Erechteion was
deconsecrated and changed to a Bishop's residence, probably for the Catholic bishops of Athens who held mass in the Latin Cathedral of
Church of Our Lady of Athens. With the advent of Ottoman control and the adaptation of the Acropolis plateau to a garrison, the Erechtheion took on its final incarnation as the
Dizdar's harem. More recent research has questioned whether the building was actually in use as a harem, however, as this is not found in Turkish sources. This final period of the building's use also witnessed the beginning of traveller's accounts and architectural recording of the structure along with its despoliation by antique collectors, including Elgin. ==Architecture==
