In the Egyptian temple, the pylon (gateway) gave access to open courts behind which lay one or two roofed and pillared halls, which provided a processional route to the sanctuary.
Egyptologists use the term 'hypostyle halls', from the Greek 'hypostylos' ('resting on pillars'); the halls were constructed so that the roof was supported by rows of columns.
