The underground relics of Samen were discovered accidentally during a construction project 1384 (2005). This Complex has been founded on a granite bed by hand and is completely under the streets, houses, and official buildings.
There have been great achievements during an eight-workshop research project. The complex includes more than 50 small and large rooms which are linked by many aisles.
These rooms have been built at a depth ranging between 3 to 6 meters. The rooms and spaces of all workshops are linked together and lead to the surface through carved stairways.
One of the features of this Complex is the existence of a lot of human skeletons buried in the floor. This shows that the complex has been used for a long period of time as a special place for burials.
In Ashkani Period, in order to prevent the four sacred elements (water, wind, soil, and fire) from being contaminated, burials were done using clay and stone coffins, away from direct contact with the four elements.
