After Building E had been explored thoroughly in four successive campaigns between 2007 and 2010 (Sissi I: 139-156; Sissi II: 143-162), in 2011 we focused on the open area north of it. This open area was first identified in 2008, when a concentration of sherds, animal bones, shells and ash was found topping what later appeared to be pit FE081, in what was then dubbed space 5.10 (Sissi I: 153 ; Sissi II: 154-155). The protruding bedrock and the nature of the excavated deposits suggested that one was dealing with an open area. Further exploration in this area allowed the identification of the south façade of Building CD, and unveiled the large open area between it and Building E (fig. 5.1 and 5.2)
