Annex/es on the south:
Three units annex. The western one - a quadrangular baptismal chapel (see below); the central one - seemingly a quadrangular prothesis chapel (see below), with a square room on its east, seemingly a sacristy.
Prothesis chapel / Diakonikon description:
A two unit wing entered from the southern aisle through an opening near the western end of the western unit, 8x4m in dimensions. The eastern unit, 4 X 4 m. in dimensions, looks like square room with an opening, but the remains on its western side might have been just the foundations of a screen. If such was the case, the two units wing constituted a quadrangular chapel. But the fact that the western unit was not mosaic paved raises a dificalty. The chapel was accessed via a doorway in the center of the southern wall of the church aisle.
Baptistery description:
Rectangular room attached to the church from southwest and entered from the narthex. 4m wide. The floor was paved with a mosaic with geometric and floral patterns. The room is divided in two by a small wall with passages on both ends. The baptismal font, hemispherical, is set in a hemispherical masonry envelop, 0.5m distant from the eastern wall. It was reveted in marble on the inside and outside. Four stairs led in from the west. Inscriptions were set in its northern, southern and western sides. The one in the western side mentions that the house was dedicated to the Trinity. The reference may refer to the baptistery, rather than to the entire church, which was dedicated to St. Stephan.
