Apvlvm – Alba Carolina Citadel (St. Francis de Paola Raveline) archaeological research programme aims to highlight the archaeological and historical potential of the area around the camp legion XIII Gemina, given that here were no extensive archaeological investigations to restore and preserve the remains of the Roman period.
The numerous constructive interventions that have succeeded from medieval times until the present, inevitably and irreparably affected in some cases, the Roman buildings. Where their tracks were preserved, it is necessary to mark out their research and particularly the restoration and conservation in situ measures, as they are important objectives of national archaeological heritage but also representative elements of identity and historical reality.
The first campaign of systematic archaeological research at this point began in autumn 2009, by investigating the northwest side of raveline.The main archaeological complex is a Roman building whose walls have been discovered at -0.40 to – 0.60 m depth, after removing a substantial layer of tegulae and Roman bricks belonging to the collapsed roof. It was discovered the SSV side of the building and several rooms. The central room is larger and the brick foundations of two rectangular pillars (0.50 x 0.50 x 0.30 m and 0.50 x 0.50 x 0.35 m) were found inside.
Walls are partial elevations and were affected in some places by the destruction of the Roman period or medieval and modern pits. Their construction technique is opvs mixtvm, with bounding courses of limestone blocks and green sandstone followed by bricks. One of the walls retains traces of painted polychrome plaster.
The Roman archaeological material is very rich consisting of considerable quantities of pottery fragments and animal bones and very commonly found types of artifacts such as sewing needles, hair pins, lamps, pieces of bronze out of which we recall a T-shaped fibula dating from the first half of the IIIrd century A.D. The numismatic material is rich, the coins are covering mainly the same period: sestertius Antoninvs Pivs (139 A.D.), denarius Ivlia Maes (218 – 224 A.D.), denarius Elagabalvs (222 A.D.), denarius Sallvstia Barbia Orbiana (225 – 227 A.D.), denarius Severvs Alexander (233-235 AD.) denarius Gordianvs III (241 – 243 A.D.), antoninianus Philippvs I (244 – 247 A.D.), antoninianus Cornelia Salonina (257 – 258 A.D). Numerous fragments of terracotta statuettes with the representation of goddess Venus (depiction Pvdica) were also discovered.
