The
complex of Sant'Andrea Priu at Bonorva is located on a rocky hill
180m high and currently comprises about fifteen prehistoric grottos,
almost all reused in the High Middle Ages and/or more recently.
The "domus de janas" open at the side of a single, vertical
trachyte block A few kilometres away from the necropolis we find
the nuragic fountain of "Lu Marzu", the nuraghe "Puttu
de Inza" and the "Monte Doma" nuraghe. A Roman
nuraghe with "hooded" tombs is marked in the area of
S. Lucia.

The
number of tombs is about twenty, arranged almost in rows, and
raised a certain way above the country plain. They are only partly
accessible, since several collapses of the trachyte rock, as well
as having destroyed some rooms, have led to the detachment of
the entrance steps.
The tombs are of the type with longitudinal projection, hence
with development of the antechamber and of the greater cella on
the same axis; one passes from the single monocellular arrangement
to both the complex pluricellular, with "pavilion" or
"corridor" type atria, and to the "palatial"
type with vast rectangular areas and ceilings held up by columns.
Three tombs stand out for their interest: the so-called "chief's
tomb", the "circular hut tomb" and the "chamber
tomb".
LThe necropolis was devastated in the Roman and Medieval period,
when it was used as a cemetery and place of worship. The Christian
burial niches and frescoes found in the "chief's tomb"
belong to this time.
DATING:
This is one of the biggest and most important domus de janas burial
grounds from the Neo-Eneolithic period, therefore between 4th
and 3rd millenium BC, linked, at least during the first phase
of their use, with the Culture of Ozieri.
