Megaron: The megaron ( ; Ancient Greek: μέγαρον ), plural "megara" , was the great hall in ancient Greek palace complexes.  It was a rectangular hall, fronted by an open, two-columned porch, and a more or less central, open hearth vented though an oculus in the roof above it and surrounded by four columns.  It is believed that the ruler of the area, called a "wanax", had his throne placed in room containing the hearth.  Because of this, the main room is sometimes referred to as the "throne room".  It was particularly Aegean, due to the open porch which was usually supported by columns.  The entrance was the feature that helps to distinguish the megaron, due to its position, which was along the shorter wall so that the depth was larger than the width.  There were often many rooms around the central Megaron, such as archive rooms, offices, oil-press rooms, workshops, potteries, shrines, corridors, armories, and storerooms for such goods as wine, oil and wheat.
