The Upper Court is the first of the three courts in the West Wing of the Palace. Its south side is supported by a strong retaining wall separating it from the West Court. On the west side, the 17 circular recesses in the ground indicate the presence of an equal number of wooden columns which probably supported a covered colonnade. The court is crossed from north to south by a raised "Processional Causeway", which, like those of the other palaces, would have been used for sacred processions and other rituals. The Upper Court also functioned as a kind of balcony from which one could watch the events taking place in the West Court, which is just to the south and on a lower level. The two courts are linked by a majestic staircase starting in the southeast part of the Court.
The buildings on the south side of the court were built much later, in Hellenistic times (323-67 BC), when the palaces had already beendestroyed. The most important of these contains a room with two columns, a central hearth and stone benches around the walls. It isbelieved to be a public building, probably a Prytaneion or Andreion.Early Christian tombs (330-600 AD) can be seen east of the "Processional Causeway"
