Dear Colleagues,

We are presented to you the proposal to hold the next congress, HYPOGEA 2026, dedicated to the study of artificial caves, in Tbilisi, the capital of the Republic of Georgia.

The foundation of this proposal lies in the fact that Georgia is particularly rich in outstanding rock-cut monuments. On the territory of the country we encounter a wide variety of sites: from ancient artificial caves, dating back to the Bronze Age and excavated through the method of heating and cooling the rock, to cave sanctuaries of the Classical period, created in the brilliant style of Roman architecture. Especially remarkable, however, are the Christian monastic complexes, comprising dozens of rock-hewn churches, refectories, and cells—many adorned with frescoes of extraordinary artistic mastery. Should HYPOGEA 2026 ultimately be held in Tbilisi, its participants would have the opportunity to become directly acquainted with these unique monuments through the planned excursions.

A second reason behind our candidacy to host this congress in Tbilisi is that Georgian scholars have accumulated nearly 150 years of experience in the scientific investigation of artificial caves in the Caucasus. To cite one example: in the early 20th century, the cave districts of Ani - the greatest medieval city of the Caucasus - were systematically studied and published in a substantial monograph by the distinguished Georgian historian David Kipshidze, a work that remains highly relevant and widely referenced to this day. From the mid-20th century onward, within the framework of Georgia’s foremost academic institution, the Academy of Sciences of Georgia, a specialized laboratory for the study of artificial caves was established. 

For decades, this laboratory functioned productively as part of the Georgian National Museum, under the leadership of Professor Givi Gaprindashvili. This scientific unit organized numerous archaeological and cultural expeditions throughout Georgia and neighboring regions, investigated well-known cave complexes, and identified previously unknown monuments. The results of these endeavors include dozens of published monographs and the organization of many academic conferences devoted to this subject.We should note that our present research group, working within the Georgian National Museum and Ilia State University, is in fact the direct successor and lawful heir of that pioneering laboratory.

It is true that over the last three decades, in the wake of Georgia’s struggle to declare and preserve its independence, the well-known political and economic crises somewhat slowed the pace of such research. Nevertheless, during the past decade a new generation of young scholars - enthusiastic and academically well-prepared - has emerged. They are poised to continue this work successfully, and the hosting of the congress in Tbilisi would serve as a powerful stimulus for them, a factor that should not be underestimated.
Now, with regard to the preparatory work already undertaken by our team for the successful organization of HYPOGEA 2026.
The event will be organized by the National Museum of Georgia, the National Agency for Cultural Heritage Presevation of Georgia, the Georgian National Academy of Sciences and the Ilia State University of Tbilisi. The Municipality of Tbilisi will be a prestigious partner of the congress.
It will be provided with the fundamental support of the Shota Rustaveli National Science Foundation of Georgia and the following foundations: “International Cultural Space” and “Tsinapari”.
