Forreddos de Janas di Martì (domus de Janas)

The hypogeic tomb of Martì called "Forreddos de Gianas" consists of three hypogeic rooms excavated in the quartz sandstone dating back to the San Michele culture; displaying pits in the pavement used for votive offerings in the atrium. It was reused in the Roman period for new burials as evidenced by the crockery found in subsequent excavations. Scattered around in the pine forest the monoliths can be found, one of which is known as S'Abbasantera, which was probably used for ritual reasons. At Forreddu ‘e Janas of Tonara there is a shape that reminds of an irregular circle with a circumference of almost 15 meters. It has two entrances, one on the northeast and one on the southwest.  The actual entrance must be the one on the southwest; in fact the northeast entrance is so irregular, it seems like it was caused by natural collapses or works subsequently carried out. From the main entrance one can enter through a small square opening the first room, preceded by an atrium. The first room is the largest and it is in the center of the domu.  The first room leads to the other two; one on the right with a small step and one in the front.
