The 2013 excavation on the church of the 40 Saints was carried out between August 8 and 27, and the work was mainly focused on the baptistery area, as well as the southern and western parts of the church. In the western part, the excavations were concentrated on the side of the staircase, and the excavation of the pits located between the limestone rocks was also continued, where a large part of the archaeological find was discovered. Sherds of amphorae and jars stand out among the archaeological finds. There are also other finds such as a glass lamp, an altar table leg, an iron nail and a coin. Excavations in the southern part of the church yielded mostly only ceramic material, where fragments of amphorae, lamps and jars, can be distinguished. Also in this area, alongside the ceramic material were discovered iron scraps, a fragment of a glass lamp, a coin etc. While in the surroundings of the baptistery, the excavations and cleanings carried out this year gave us new data regarding its many rooms. Thus it was discovered that the baptistery consisted of 9 individual or collective baptismal bathtubs, two pools and some other rooms. The baptismal bathtubs are positioned mainly in the side naves, porticoes and also in one of the underground galleries. Due to the presence of the walls built in the XX century by the army, it was impossible to continue the excavations in the northern part of the baptistery. As for the other rooms, they have a quadrangular shape, with two floors paved with stone slabs and in almost all cases they are equipped with a bench.
