83 The Excavation of Building CD 5. 5.1. Introduction Florence Gaignerot-Driessen Quentin Letesson Following the 2007-2008 campaigns, the presence of a large Postpalatial building in Zones 3 and 4 on top of the Buffo hill at Sissi has been established (Gaignerot-Driessen & Letesson 2009: 113-114). The irst two years of exploration have also made it clear that the site preserved traces of an earlier occupation (spaces 4.1-4.3, see Letes- son 2009: 132). The 2009 and 2010 excavation campaigns concentrated on deining the limits of the building and on the investigation of its rooms and spaces to the latest level of occupation. In addition, a few, limited tests were conducted, in the hope to clarify the earlier phases. The remains on top of the hill cover an area of approximately 750 m 2 (igs 5.1. and 5.2).
