The hypogeum is excavated on a low limestone bench, located halfway up a steep slope that slopes down a valley groove crowned on the north by limestone walls.
The facade describes a wide arch in the center of which the centered stele stands out. The lower part of the stele appears to be divided by a band from the lunette motif above. The entrance has been considerably remodeled: it is unclear whether the two steps that serve as a bench-seat framing it were already originally interrupted for the opening or whether more likely the upper one coincided with the lintel of the doorway.
Behind the access door is a short corridor that leads into a cell with an oval floor plan and from which there is a niche on each side. The ceiling appears concave; a cupola opens towards the bottom in the floor level: a second, smaller ditch is dug near the entrance and a gully converges there, which also crosses the floor level of the exedra.
As usual for this monumental typology, the rock is cut at the top to create the so-called upper exedra where in the center is the mound, which near the stele preserves traces of two holes (originally three) where betilini were drilled to express magical-sacral concepts.
Both the upper and the lower exedra have quadrangular recesses of various sizes, i.e., basins dug into the rock that are believed to be postholes, and which are nothing more than an ingenious rainwater collection system carried out later.
