House X is by far the largest and best appointed of the Minoan houses excavated at Kommos in south-central Crete, a Minoan harbor and settlement that later became the site of a Greek sanctuary. Situated on the seacoast of the western Mesara Plain, Kommos faces west toward the Libyan Sea. House X stands on the southern edge of the Minoan town, separated by a large slab-paved road from the monumental civic buildings built and used between the Protopalatial and Postpalatial periods. The description of the stratigraphic excavation of this elite house is published with numerous architectural plans along with the catalogued small finds and tables of data on the floral and faunal materials. The excavated fresco fragments are also discussed and illustrated.
