Geophysical Investigations within the Latus Dextrum of Porolissum Fort, Northwestern Romania—The Layout of a Roman Edifice

This paper summarizes the results of a recent geophysical investigation carried out at Porolissum, which is considered to be one most significant Roman sites in Romania. The survey was within latus dextrum fort, same location that had been subject earlier surveys as well older archaeological excavations (1970s) uncovered multiroom building. A cesium vapor total field magnetometer and multi-electrode resistivity meter for dense Electrical Resistivity Tomography (ERT) were used. Eighty parallel ERT profiles combination with emerging magnetic data an antecedent allowed us complete more precise interpretation regarding building once existed on left side Porolissum’s Principia (the commander’s house). In contrast survey, only reveals part building’s architecture, provides comprehensive view structure’s layout. More than 20 rooms could positively identified, existence further might deduced from data. scan revealed northern external wall well, not reflected map. Because some parts are visible map, we can assume constructed least two types rocks (magmatic sedimentary). addition anomalies, number discussions concerning connection between our geology area held. complementarity prompted conceive preliminary 3D reconstruction Even if function unknown absence reliable data, it have storage building, second praetorium, valetudinarium (hospital), or armamentarium (weapons building). illustrative completed taking into consideration military hospital, which, based available may credible assumption.
