Southwest Area - Industry and Houses Leaving the area of the boundary stone, one can head southwest up a valley leading toward the Pnyx, meeting place of the Athenian assembly. Here are the complex remains ... These Athenian private houses were small, turning their blank faces to the street and deriving light and fresh air from an interior courtyard. Walls were of sun-dried mudbrick on stone foundations, with tiled roofs; most floors were of beaten clay with only occasional mosaics. ... One larger structure, the so-called Poros Building, has a long corridor flanked by square rooms, with a courtyard at the rear (Fig. 28).
