Near the rural church of S. Maria de Trempu, behind the pretty stone houses used during the novena, there is access to an isolated domus de janas dug out of a solitary block.
In order to reach the novena church, follow the SP 23 from Ghilarza for about 7 km. Turn right towards the Santa Maria Ausiliatrice novena church and here you’ll find the Domus De Janas close to one of the muristenis (small houses for pilgrims).
