ABSTRACT
The authors of this paper performed an architectural survey to approach the study of the south aditus maximus of the Roman Theatre in Málaga, which is covered by a sloping barrel vault topped by a round arch, all made with stonework.The analysis of the survey has generated valuable information to deepen knowledge of Roman stonework techniques, above all those related to stone stereotomy, which involve the resolution of geometric problems in space and their material execution. The authors have formulated hypotheses about the design and construction strategies used, such as the division into parts and their assembly, the number of courses, locking systems, the orientation of the bed joints, vault springers and their transition to the walls, or carving methods. The solutions used in this vault are compared to others used in Roman times, analysing possible knowledge transfers and establishing analogies in the construction resources used.
