After the mid-3rd millennium BC, the new settlement with the large square houses gradually took over the whole of the terraced slope of the mound, showing an urban layout with roads, open areas and water channels. The shape of the houses, the hearths, the ovens and the construction techniques are all found in other sites in northeastern Anatolia, and were to remain unchanged till the end of the millennium. In the middle of this period a series of oval constructions were built, partly underground and with the access through small staircases, whose use is difficult to reconstruct because of the lack of any in situ material or installations.
Excavations have shown that on the edge of the settlement was a stout wall, built of mud bricks and resting on an imposing stone base, with a semicircular bastion; it is the first evidence we have of the construction of a fully-fledged urban fortification.
The settlement pattern of the plain is based in this period on the presence of numerous fortified towns, which suggests that there was a growth in the size of the population without the parallel formation of complex territorial political structures. Even though the Malatya region seems to be once again dominated by Arslantepe, which was considerably larger than all the other settlements, the plain has evidence of many sites, probably with a certain degree of regional conflict between them.
The painted pottery of this period is very finely made with complex and codified motifs, which were certainly produced by skilled craftsmen whose products circulated widely within the regions of Malatya and Elazig.
