As houses were built on top of earlier structures, the windows and doorways were blocked up. Notice the changing alignments as the walls were remodeled.

The reconstructed brick wall is covered each year with a protective coating of clay and straw plaster. The original structure and unexcavated levels remain safely buried beneath a layer of bricks and back dirt.

The Trench 11 area showing the perimeter wall (on the left), the curtain wall, and the Period 3C drain that cut deeply into the Period 3B deposits (see the labeled plan in 72). The sediments outside of the perimeter wall are hard packed ashy debris
