Expanding Underground 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.”

Dear Colleagues and Friends of the Tunnelling and Underground Space family,

It is with great pleasure on behalf of the Greek Tunneling Society (GTS) to invite you to the World Tunnel Congress 2023 that will be held in Athens – Greece, from the 12th to the 18th May 2023.

Athens, the city of myths, monuments, gods and ancient glory could offer unique experiences for the distinguished delegates of the ITA family. Contributions from all parties of the supply chain of the underground industry i.e. consultants, contractors, software producers, machine / equipment manufacturers, investors as well as operators and clients are welcome to attend since they will be able to exchange knowledge, promote their expertise / knowhow and define future needs.


Chair of the Organizing Committee
ITA – AITES World Tunnel Congress 2023 / Athens

The theme of WTC2023 “EXPANDING UNDERGROUND”, will focus on the Knowledge and Passion that our industry offers to Make a Positive Impact on the World.

During the last 5 – 6 years Greece experiences an explosive recommencement of the construction sector including large scale infrastructure projects, along with numerous tunnel and underground projects within the complex geological environment of the country. Such coincidence offers various opportunities for exciting technical tours during the congress.   

The Venue of the Congress ”Megaron Athens International Conference Centre” is located in the city centre offering a unique opportunity for the delegates to explore, in parallel of the congress, the unparalleled beauty of the rich inheritance of ancient monuments and artifacts. Moreover, mid-May is an ideal season to visit Greece which is located in a blessed natural environment and surrounded by the “deep blue” Mediterranean Sea.

While GTS is getting prepared for an in-person WTC2023 participation, as we all vigorously anticipate restoring our lives to normality, there will also be an option for a virtual participation. Hence, WTC2023 will be carried out in hybrid mode.

GTS is committed to organize a successful and memorable ITA-AITES World Tunnel Congress 2023 and offer what has been known as a traditional Greek hospitality.

We are looking forward to welcoming you in Athens.
