The south end of the West Court is occupied by four large stone-built structures known as "Kouloures" (rings) ,belonging to the Old Palace complex. The workmen on Evans' excavation gave them their name when they were first discovered at Knossos. Similar pits were also later discovered at the Palace of Malia. Their exact use is unknoun, although today they are generally regarded as depositories for offerings from the Palace shrines, or granaries.
In front of the Phaistos "Kouloures" passes a "Processional Causeway" which starts in the West Court. One of the "Kouloures" is cut across by a cobbled road built in later years.
The well next to them belongs to the Hellenistic period (323 - 67 BC).
