Excavations continued around Castel Nuovo in piazza Municipio.
The investigation continued with the exploration of the north-western part of the bastioned wall surrounding the second ditch and the buildings inside it, already partly uncovered. The wall delimiting the castle’s first ditch, the line of which is partly retraced by the present wall, was identified. This was a low crenellated structure dating to the restructuring of Castel Nuovo ordered by Alfonso d’Aragona. The facing was preserved on the north side almost to the top, whilst on the south side it was preserved from circa 4.75 m a.s.l. to a height of circa 3.10 m as it was cut into by modern reconstruction.

This wall was respected even when the bastioned wall was built in the period of the Viceroy in the 16th century. The excavation revealed that, in this period, to the south it partly delimited a sloped surface which extended as far as the southern frontage of the rooms present in the second ditch and constituted one of the routes used for movement inside the ditches and communication between the latter and Castel Nuovo. This ramp, identified by a series of overlying beaten surfaces, with cart tracks impressed in their surfaces, datable to the 16th-19th century, was linked to the gate of the so-called Aragonese citadel. Below these floor levels the excavation revealed a stratigraphic sequence of rubble, obliterating earlier structures for which a date was indicated by the 15th century pottery found in the obliteration layers.

Investigation also continued inside the building which stood in the second ditch. The rooms, belonging to these structures, functioned as arms stores, as attested by iron and limestone cannonballs found during the excavation. Although dating to between the end of the 16th and the 17th century, the continued research has begun to reveal earlier phases with different functions and a different layout of the area.
