The South Baths and West Sanctuary Project (2013-2015) is undertaken by the American Excavations at Morgantina (AEM) under the auspices of the Parco Archeologico Regionale di Morgantina and the authority of the directors of the AEM, Malcolm Bell III (University of Virginia, Emeritus) and Carla Antonaccio (Duke University). It aims to fully excavate a Hellenistic public bath complex (South Baths) and an adjacent building, identified as the West Sanctuary of Demeter and Kore in the Contrada Agnese area of the ancient city. Both buildings were first excavated in 1971 and then again briefly explored in 2005, with excavations renewed in 2009 and 2010.

The first field season of this new project (2013) focused on the South Baths complex, aiming to reconstruct the extent, design, accessibility, circulation patterns, decoration, bathing program, water management systems, overall function, date and developmental history of the building, as well as its relationship to the surrounding urban landscape of the Contrada Agnese area of Morgantina.

Following a thorough cleaning of parts of the baths that had been excavated previously, work was extended into parts of the building that had not been studied systematically before. In terms of overall plan, the full extent of the building was identified both along its E-W and its N-S axis. It largely follows a rectangular plan (although this is not as yet fully defined) with a rectilinear interior layout. The design of the identifiable bathing rooms is unusual: the characteristic unit of tholos with two small ante rooms with benches, as known from the North Baths at Morgantina and the baths of Syracuse and Megara Hyblaea, appears to be absent. While a full assessment of the bathing program of the South Baths must await complete excavation of the building, even at this point it is possible to identify remarkable differences between the South Baths and North Baths (and other Sicilian baths complexes).

Several rooms had opus signinum paved floors that remain in various stages of preservation. A particular focus lay on excavation of the bath furnace: the eastern part of this was excavated to a level of secondary use (as a cooking oven), in its western part the original levels were reached. It could be shown that room 9, previously incorrectly identified as a suite of two bathing rooms, actually served as a water reservoir.
