Several trenches were opened in various parts of the site. In the south-west sector two trenches were opened in order to gain a more precise plan of the calidaria “e” and “d”. However, this area had suffered severe disturbance caused by mechanical diggers in 1988. In fact, traces of a bucket from one of these machines were identified on the floor levels of the hypocausts and the walls were almost razed.

Between them the north and east areas revealed the complete stratigraphic sequence.
North of the praefurnium “g”, room “h” (probably the wood/coal store), was completely excavated and provided useful information regarding both the nature of the eruptive fill of 472 A.D. and the wood used for heating the rooms in the bath complex. Above room “h” there was a cistern “i”, also completely excavated. Following the 472 eruption, the cistern was emptied and used, together with other parts of the northern area of the site, and later buried by the ash from the 505/512 A.D. eruption. Numerous carbonised leaves were found within this layer which, together with the anthracological samples taken in previous years, provided a reconstruction of the late antique cultivations in the Vesuvian area.
During this season mortars samples were also taken and a three-dimensional scan was made of the site.
