The archaeological tunnels and excavations of Jerusalem's Old City received recognition from the International Tunneling and Underground Space Association (ITA) this year, during the ITA's most recent award ceremony.

The tunnels earned the top spot in the "Oddities of the Underground" category unique to the ITA Tunneling Awards.

The 2020 awards, given out virtually due to the coronavirus pandemic, were focused on various innovations and accomplishments in the field of tunneling. Awards are not purely archaeological in nature, and in fact most of the eight categories were given to projects related to railroads and construction.

But Israel's project is very archaeologically focused, especially given the rich history that lies beneath the surface of much of the country, especially in cities thousands of years old like Jerusalem.

And it is in Jerusalem where much of the real innovation in archaeological tunneling can be seen.

The awarding body placed the tunnels in the oddities category, considering the excavations attracts millions of tourists each year — putting the findings on full display — even while "the entire extent of the archaeological site has not yet been fully explored."

The process in which the tunnels are made, and then made available to the public also earned the archaeological site consideration within the category.

"Tunnel design and building expertise in soft grounds and archaeological fill is required in order to proceed with the excavations and make the site accessible to the public," the ITA said on its website. "Excavation is carried out underground, manually, using steel ribs and steel plates as temporary and permanent support.

"The sensitive environment demands great dexterity and flexibility."

Additionally, the unique manner in which the findings of the site are collected and the technologies used to carry out the excavations forwarded the tunnels' place within the category.

"Due to site complexity derived from small excavation area and risks of shallow tunneling in urbanarea, special excavation technologies are executed, such as custom-made drill machines adapted tosmall spaces," the awarding body said. "In addition to that, special measures are to be taken in order to consider the archaeological findings and to protect them during excavation.

"Unlike conventional excavation in which the muck is being moved away, the nature of this project is to keep the muck for further research by scientists."
