The main facade of both the Old and the New Palace looked onto the West Court, off which the official entrances to the Palace opened. The facade which can be seen on a lower level belongs to the Old Palace(1900- 1700 BC). It is indented according to the rules of Minoan architecture. The lower part of the walls is constructed of massive limestone blocks (orthostats). The entrance is set into a recess in the SW corner of the court. lt consisted of a monumental porch with a large central column from which a splendid corridor, paved with gypsum slabs, led to the Central Court. This old entrance is now interrupted by the buildings of the New Palace.
Higher up and 7 metres further back is the facade of the New Palace (1700-1450 BC). It is constructed of large ashlars and also has deep indentations and protrusions. There are two entrances leading to the interior of the Palace. The main entrance is on the north and consists of a monumental staircase leading to the Propylaea. The other is deeply recesed and leads via a wide corridor to the Oentral Court, crossing the West Wing of the Palace

The impressive staircase starting in the west Court led to the monumental Propylaea, the principal and most impressive entrance to the New Palace (1700-M50 BC). The portico consists of a central column - only the base is preserved today - flanked by pilasters. There followed a solid wall with a double opening and a colonnade of three columns. The floors of the Propylaea complex were paved with gypsum slabs which gave it a sumptuous appearance. The colonnade opens onto a large open-air light-well through which rainwater drained away.
There are two accesses from the Propylaea to different parts of the Palace. The first access, in the hall with the colonnade, led via a staircase and corridors to the Peristyle and thence to the "Royal Apartments".
The second, in the SE corner of the light-well, led to an inner staircase which ended in the Antechamber of the Magazines and the Central Court of the Palace.

The magazines of the Old Palace(1900-1700 BC) occupied a large part of the West Wing immediately to the east of the West Court and extended to the lower terrace. Apart from their use as storage areas, they also appear to have housed some of the workshop activities of the Old Palace. Today most of the magazines have been filled in.
One of these is the magazine with the giant pithoi (storage jars) decorated with discs and rope patterns in relief. Just east of this is a well-preserved quern installation for grinding grain. There is another well-preserved Old Palace magazine under the floor of the light-well in the Propylaea.

The north part of the West Wing is occupied by she large complex of the palace magazines or store rooms. It consists of the antechamber, the corridor of the magazines and the magazines themselves. The first wide hall forms the antechamber of the magazines and opens off the Central Court via a doorway with a central column and two pillars. Two other columns inside the room supported the roof. Under the floor of the antechamber was discovered the Archive Room of the 0ld Palace (l900 - 1700 BC), containing over 6.000 clay sealings, i.e. seal impressions on balls of clay, which were used to monitor the movement of the goods in the magazines(fig 1).
A double doorway with a central pillar on the west side of the antechamber led to the corridor of the magazines, with a second central pillar supporting the roof of the corridor. To right and left were the ll magazines, in which the goods produced by the Palace were stored. The westernmost magazine, on the north side of thecorridor, which has been roofed over by the excavators contains tall pithoi (storage jars), one of which bears an inscription in Linear A (fig.2)

Almost the whole south part of the West Wing was dedicated to the shrines of the New Palace. The main architectural types of shrine are the "Bench Shrine" and the "Lustral Basin".
The first type consists of small, rectangular rooms with low benches running round the walls, perhaps to support cult objects and figurines of the deity. On some of them were found female figurines, ritual vessels and "Offering Tables" (small altars). On the walls of some rooms are incised sacred symbols, such as the double Axe and the star.
The "lustral Basin" type consists of rooms which are set somewhat lower than the surrounding structures, with a few steps leading down into them.
The were usually lined with slabs of gypsum, giving them a highly - finished appearance. Although it is doubtful that these structures contained water, it is thought that they were used for purification rituals.
There is a third type of Minoan shrine in the S-E part of the shrine wing. Its is a room with central pillars (Square, stone - built columns) thought to be a cult area, similar to the "Pillar Crypts" of the Palace of Knossos, where the sacred pillar was worshiped by pouring libations.

The great Central Court is a basic architectural element of Minoan palaces and the core around which the different wings are set. It was the focus of the economic, social and religious activity of the palace, the setting for events which could be watched from the windows and balconies.
The Central Court of the Palace of Phaistos was built in the time of the Old Palace (1900-1700 BC). It was also used in the New Palace with minor alterations to its orientation and dimensions. It is a rectangular paved, open area with colonnades running along both its long sides, with alternating pillars and columns which supported open colonnades.On the west side of the court, two adjoining rectangular rooms with benches, open on to the Central Court, may have been "sitting rooms" for the spectators watching the events taking place in the Central Court. In the east colonnade of the court, some stone-built benches next to a water cistern may have formed islands of rest and recreation.
The stepped structure in the NW corner of the court may have been an altar for the ceremonies which were held here.
The pithoi (large storage jars) in front of it were found in buildings founded in the site of the Great Court after the destruction of the Palace.

The North Wing is one of the most important wings of the Palace, as it is believed to have housed the "Royal Apartments". lt also contained sets of rooms, inner courtyards, corridors and staircases leading to the upper floor. The splendid gateway on the north side of the Central Court led to the complex of the "Royal Apartments". It is framed by two magnificent wooden half-columns, now reconstructed.
On either side of the gateway are two niches decorated with wall paintings, in which the gate guards may have stood. Behind the gateway is a wide corridor with a drainage duct, which led to an inner courtyard, which in turn led to the "Royal Apartments" complex.
The term "Royal Apartments" was established by the excavators, who followed the terminology applied by Evans to similar areas at Knossos. They are undoubtedly official apartments with particular architectural features, such as open balconies and colonnades, polythyra (pier-and-door partitions), lightwells and "Lustral Basins". The gypsum slab flooring and colourful wall paintings gave these apartments a particularly luxurious appearance.

The open peristyle court was one of the most elegant inner courtyards of the New Palace. It consisted of an impressive peristyle with four columns on each side supporting the corresponding colonnades, while the central area remained open. The same construction appears to have continued on the upper floor, with a second row of columns.
The peristyle court was a focal point of the Palace with access routes leading from here to the "Royal Apartments", the Propylaea and the Central Court.
The ruins visible on a lower level in the centre of the peristyle belong to a house of the Prepalatial settlement (3200-1900 BC).

The northernmost of the "Royal Apartments" has been identified as the King's Megaron and bears a striking resemblance to the corresponding "King's Megaron" at the Palace of Knossos. It consists of a spacious central hall with impressive polythyra (pier - and - door partitions) on the north and east sides. The east polythyron communicates with a second room with two columns, which opens onto a large light-well to the east. The gypsum slab flooring with red plaster filling, the interstices, gave the whole complex a particularly sumptuous air.
The north side of both rooms opens onto a spacious colonnade with columns set far apart, offering a magnificent view of Mount Psiloritis and the sacred Kamares Cave. A long corridor at the back of the polythyron room leads to the impressive "Lustra1 Basin" of the Megaron. The whole apartment was decorated with colourful wall paintings depicting linear and plant motifs.

The southernmost of the "Royal Apartments" ofPhaistos has been identified as the Queen'sMegaron. It consists of a beautiful, spacioushall with a double colonnade opening ontoa light-well. The floors are paved with gypsum slabswith red plaster filling the interstices. Gypsumwas also widely used for the benches runningaround the walls of the Megaron and the facingof the lower part of the walls. The upper walls aredecorated with frescoes depicting plant motifs. Twobeautiful rhyta (libation vessels) were found here: one is decorated with the cult symbols of thedouble axe and sacral knot, while the other bears areed pattern.
The two staircases to west and north led to the upper floorof the Megaron and the peristyle, where one of the mainentrances to the "Royal Apartments" was located.

The complex of four rooms on the northeast edge of the Palace does not belong to the Old Palace, although it directly adjoins it. In the westernmost building is an elongated rectangular room with partitions of vertical clay slabs. Similar "cists" in the Palaces of Knossos and Zakros were used to store valuable ritual vessels. Here they were found empty. Next door, in the narrow rectangular room to the southeast, was found a clay tablet inscribed in Linear A and the famous "Phaistos Disc" bearing hieroglyphic writing. The building was therefore named the Palace "Archive"
The building east of the Archive is thought to be a shrine or the archivist's residence, while the easternmost building is known as the "Potter's Workshop" because a large number of unfinished pots were found there. The intermediate building has an impressive peristyle of alternating pillars and columns. A staircase on the south side of the peristyle building connects the whole complex to the NE entrance to the Palace, which stood in this spot.

The east part of the North Wing forms the workshop area of the Palace. It consists of the East Court and a complex of small rooms which are believed to be the workshops of the New Palace (1700-1450 BC). Approximately in the centre of the court are the ruins of a horseshoe-shaped kiln. The elongated rectangular building with 6 rooms on the west side of the court appears to have been used for the workshops of the kiln craftsmen.
The square room on the north side of the court was the gatehouse of the northeast entrance to the Palace. It has gypsum slab flooring and benches around the walls. Behind it is a long corridor leading to the inner courtyard of the North Wing and thence to the "Royal Apartments"

The church of Agios Georgios (St. George GR: Αγιος Γεώργιος) Phalandras stands a little to the south from the Palace of Phaistos on the road to Agios Ioannis village. The church was the monastery church of the Orthodox male monastery of the same name, dated to the early Venetian period (16th century), which operated normally until its dissolution in 1821. The ruins of the fortified building complex around the church were still visible until the first decades of the 20th century.
