Editing Pergamon (section)

===Housing===
Generally, most of the Hellenistic houses at Pergamon were laid out with a small, centrally-located and roughly square courtyard, with rooms on one or two sides of it. The main rooms are often stacked in two levels on the north side of the courtyard. A wide passage or colonnade on the north side of the courtyard often opened onto foyers, which enabled access to other rooms. An exact north–south arrangement of the city blocks was not possible because of the topographical situation and earlier construction. Thus the size and arrangement of the rooms differed from house to house. From the time of Philetairos, at the latest, this kind of courtyard house was common and it was ever more widespread as time went on, but not universal. Some complexes were designed as [[Prostas house]]s, similar to designs seen at [[Priene]]. Others had wide columned halls in front of main rooms to the north. Especially in this latter type there is often a second story accessed by stairways. In the courtyards there were often cisterns, which captured rain water from the sloping roofs above. For the construction under Eumenes II, a city block of 35 x 45 m can be reconstructed, subject to significant variation as a result of the terrain.<ref>''Altertümer von Pergamon''. XV 3.</ref>
