The GTS has been the national representative of Greece in ITA-AITES since its creation 25 years ago. The Greek Tunneling Society has been continuously participating in the ITA-AITES activities (General Assemblies, Working Groups etc), whereas the Greek Young Members Group has been actively involved on the initiatives for the networking of young tunneling professionals and students as well as on bridging the gap between generations of tunnellers.
During the last 4-5 years Greece experiences an explosive recommencement of tunnel construction activities just after country’s recovery from the economic crisis. Some 65km of, total single tube length, tunnels were recently completed along the four motorway concession projects and approximately 20km long tunnels including 24 Metro Stations in total are near completion, both for the new Athens Metro line 3 and for the Thessaloniki Metro. Moreover, numerous underground projects are planned to commence shortly within the complex geological environment of the country.
The organization of WTC in Athens will greatly promote the interests of the ITA in the Balkan region where, despite the length of the coastline (Greece alone is classified as the 11th country worldwide in terms of length and 2nd country worldwide in terms of coastal length vs country’s land area ratio), the mountainous environment of the countries as well as the rapid urbanization necessitates the construction of longer – deeper – larger – safer – smart – sustainable and green underground projects.
Greece has been for many millennia the cross road for civilizations. This has left a rich inheritance of ancient monuments and artifacts of unparalleled beauty. Having a magnificent natural environment and surrounded by the “deep blue” Mediterranean Sea, it provides perfect conditions for recreation. Mid May is an ideal season to visit Greece. While the city of Athens is not that crowded by Tourists, the climate is warm enough for enjoying outdoors and the beaches.
Being in Athens, one of the World’s safest city, you’re midway between Europe, Asia, and Africa; constituting an easily accessible destination city from all over the world. The proposed Venue of the Congress ”Megaron Athens International Conference Centre” offers a stunning environment with exceptional aesthetics, but also cutting edge technology. Moreover, it is situated in the city Centre, next to the “Megaron” Metro Station, which enables easy access from all over the city.
Athens provides abundant modern hotel accommodation and boasting an excellent METRO system. It presents great opportunities for sightseeing, excursions and technical visits. Numerous hotels are within walking distance from the convention centre, located in central Athens, as well as from other places of interest.
We are committed to organize a successful and memorable ITA-AITES World Tunnel Congress 2023 and offer what has been known as a traditional Greek hospitality.

KNOWLEDGE & PASSION TO MAKE A POSITIVE IMPACT ON THE WORLD
Rapid urbanization, natural hazards, climate change and extreme weather phenomena, sustainable energy geo-resources, people’s mobility and transportation of goods are first-priority demanding challenges that the globe is facing.
Cities, infrastructure and logistics expansion towards underground provide safe, sustainable and green solutions facilitating the transformation of millions of people’s lives into a more resilient lifestyle. A comprehensive understanding, rethinking and reshaping of the underground spaces has become even more vital and crucial in the urban transformation of future cities, where overground space will be more and more valuable. For the latter to be attained, a holistic approach is required not only in terms of spatial organization or overcoming engineering challenges, but also with regard to the establishments of policies, regulations and consideration of social factors.
WTC 2023 in Athens will highlight the multiple advantages and solutions that underground space can provide, at the prospect of a whole new era of smart technology where sophisticated “digital tools” change investigation, design, construction and operation methods and strategies rapidly. WTC 2023 will additionally provide an ideal opportunity to showcase recent innovations and the perspective of technology to further efficiently upgrade underground infrastructure assets, transforming the industry and the societies it serves.
We strongly believe that WTC2023 held in Athens (Greece) will provide a valuable opportunity and a fertile soil for the international underground society to make a literally positive impact on the world.”

EUPALINOS Tunnel - Samos Island
An International Tunnelling Landmark
The Eupalinos Tunnel is considered as one of the most important engineering achievements of antiquity. It’s a 1036m long tunnel in Samos Island, Greece, built in the 6th century BC to serve as an aqueduct.
The Eupalinos Tunnel is considered as the first underground project excavated with a geometry-based approach. The Engineer Eupalinos built a tunnel under a mountain by starting to dig, simultaneously, from two portals diametrically opposite. All applied measurements using maths and geometry are of outstanding precision.
It is estimated that 8-10 years were required to complete the project. The maximum overburden of the tunnel is ~ 170 m below the summit of the Kastro mountain and its elevation is 55m above sea level. The tunnel consists of a corridor having internal dimensions 1.80×1.80m and of a ditch 0.60m wide. The depth of the ditch ranged from 4.0m in its northern section to 8.9m in its southern one…
