[Iran] - Enormous underground city in central Iran made national heritage

INSUBCONTINENT EXCLUSIVE:
is one of the largest underground areas in Iran and even in West Asia.Two archaeological seasons have been carried out on the underground
city so far and subterranean spaces and passageways covering 400 square meters have been excavated by archaeologists and cultural heritage
experts.The underground city was accidentally discovered several years ago during a construction operation
Narratives say that it sheltered inhabitants during the Mongol invasion of Persia in the early 13th century.The hand-carved underground city
can become a top tourist destination for domestic and international tourists, but there will need to be more accommodation options,
including eco-lodges, according to local authorities.Based on the academic findings, the creation of handmade troglodytic architectural
sites depends on several factors including climatic and geographical conditions, defense, security, durability, and religion, which were
deeply tied with the cultural, political, social, and economic circumstances
This architecture can be classified into various formal types in terms of their external form, internal space, and function (religious,
tombs, residential, and shelter).The handmade troglodytic architecture is a distinctive kind of architecture, which does not require major
construction materials and consequently very low environmental load since its creation is majorly by extraction of space rather than the
addition of mass
Architecture by subtraction rather than addition provides many opportunities that call for comprehensive research and analysis.As there is
no obligatory method in making spaces rather than material cohesion, there is no priority in constructing a troglodytic structure, either
from the roof or from the floor
Dealing with stone blocks, rocks, and piles of the earth requires a variety of tools as an ax, hammer, chisel, and sledgehammer to shape the
interior space.In Iran, many magnificent cases of this architecture have taken place in different regions due to its various climates
This unique architecture is at odds with the conventional settlement patterns and construction methods and is always can take advantage of
the mountains and valleys on the floor or wall, which is a good way to control climate fluctuation in different regions.Iran is a haven for
ancient troglodytic architecture which is somewhat forgotten though they are filled with life and creativity
The northwest Kandovan village is one of the most famous examples of troglodytic architecture in the country; its ice-cream cone-shaped
