Following conservation works in the palace and parallel stabilization measures of the fortification walls, the implementation of the conception for preservation and presentation of the different historic housing settlements in the extensive area of the Unterburg commenced. In the northern part final excavations of the Maran team and further archaeological studies of the Ephoria team in the western part had been undertaken in the years before. Mainly to be shown are Early Heladic houses with a round apsis in the eastern part, strong stone wall buildings of the so called Palace Phase in a lower level of the western middle part and some houses of the later so called C-Phase on the upper level in the southern half of the Unterburg. In the north a corridor of stone walls leads to the North Gate. South-west on the bottom of a deep trench the alignment and filling of the earliest city wall is to be seen. The conservation treatment of the ruined wall relics is mainly characterized by stabilization works in different, but mostly simple techniques by hand with a mixture of lime mortar to fill up the joints and partly to remove and replace damaged wall parts. The levelled crowns of the restored walls indicate the structure of the different housing phases.
