Well illustrated with photos and plans, this volume reports on inspections carried out in 2004 of underground structures related to the ancient Armenian capital of Ani. The 2004 mission checked the status of the dwellings with respect to the investigation of 90 years before, to undertake a detailed exploration of some selected dwellings chosen as term of comparison, and to investigate with special care those underground structures which were inside or close to the city walls, in order to establish the relations between the town and the underground sites.
