This was the second season of excavations carried out by Milan University at Monte Zara, locality of Is Obias, in the territory of Monastir (CA).
New investigations in the previously explored area took place in five zones, which were revealed to be of great interest (Figs. 1-2).

1) Entrance to the fortified area: the monumental gate, identified in 2015, was uncovered in its entirety. The curtain wall, which wound along the east side, was built on the bedrock (Fig. 3).
2) The central walkway was freed of the collapsed material that obliterated it as far as the south-western excavation edge, reaching the rock on which the lateral containing walls were also built (US 10 and 15). It was only possible to trace a patch of beaten floor surface (US 55) in the section of the excavation edge. It may be suggested that this surface levelled the uneven rock surface across the area. The entrance of a small rainwater drainage channel was identified in correspondence with and underneath the offering table already noted during the 2011-2012 campaign. The channel was incorporated and reused in the eastern wall facing was (Fig. 4).
3) In order to evaluate the channel and its relationships with adjacent contexts, a trench was opened to the exterior of wall US 10, where the collapse of the wall itself (US 58) emerged, down to the bedrock.

4) In sub-circular room Alpha, situated to the north-west, further excavation confirmed the lack of an entrance. This room’s function remains uncertain.
5) Towards the west, a rectangular room (Beta: US 21-24.54) was built using the earlier curtain wall US 16 to close its east side (Fig. 5). A sandstone basin, perhaps relating to a basin ‘rotunda’, was reused in the perimeter wall US 24.
