Introduction to WTC2023
The Greek Tunnelling Society, organizes between 12 – 18 May 2023 the World Tunnel Congress (WTC2023) in the city of Athens. The WTC is the premier annual event of the International Tunnelling Association (ITA-AITES) and is considered as the top attended tunnelling conference in the world with the participation of more than 2000 professionals. The congress will take place in the international conference center MEGARON which is considered as one of the finest and most technologically advanced conference venues in Europe.
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. WTC 2023 in Athens, that will be carried out in hybrid mode, will highlight on 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.
The congress covers all “hot” topics of the tunnelling and underground space industry, whereas a high scientific level will be ensured as all papers, prior to publication, will be peer reviewed by highly skilled professionals and academics coming from all parts around the world. The total number of the members of the scientific committee exceeds one hundred fifty (150), while all accepted papers for publication will be made available to an open access portal via the platform of a highly esteemed international editor. Hence, the research / work / best practice / efforts of the authors participating in the WTC2023 will be freely and permanently available so anyone, anywhere, can read and build upon his / her / them work.
WTC2023 will also host a large exhibition with plenty of space, where traditionally all major international firms involved in the tunnelling industry participate.
The program of the WTC2023 will start with the training courses of ITACET between 12 to 13 May 2023, whereas the main congress activities (i.e. scientific program and technical exhibition) will take place between Monday (15/5) and Wednesday (17/5). During the whole congress week, all regular annual ITA activities will be organized (i.e General Assemblies etc), along with the various meetings of the working groups and of ITA’ s committees. Last but not least, thanks to the construction activity that will take place in Athens by 2023 several technical visits will be organized providing to the delegates various alternatives to choose upon.
Athens, a vibrant modern European capital situated by the Aegean Sea, is an ideal location for international conferences. Following the unprecedented circumstances that the pandemic caused and after tolerating while within a pandemic, for almost two years, the necessary social distancing, the lockdowns and the long-lasting travel restrictions, the need to hold a conference with a physical presence has become a great desire for all of us and we look forward to this moment with great anticipation. Thus, timeless Athens sounds like the ideal conference host city and the meeting hub of the tunnelling and underground space professionals, thanks to the pleasant climate conditions during mid-May and its unique blend of history, art, culture, lifestyle and entertainment.
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.

WTC through the years
The World Tunnel Congress (WTC), organized by the International Tunnelling and Underground Space Association (ITA), is the world’s leading and most internationally recognized tunnel forum.
Since 1974, when the International Tunnel Association was founded on the initiative of nineteen nations, the World Tunnel Congress stands out for 49 consecutive years.

Tarcisio Celestino was previously ITA President (2016-19) and President of the Brazilian Tunnelling Committee. He was the Animateur of the ITA Working Group 12 on Sprayed Concrete Use (2005-10). He earned his doctorate degree in Civil Engineering (Rock Mechanics) from the University of California, Berkeley (1981).
He is currently Professor at the University of Sao Paulo and employed by Themag Engenharia Ltda., Sao Paulo (Brazil), where he leads the Geotechnical Engineering, Engineering Geology &Transportation Engineering Design Groups. He is also responsible for the geotechnical designs of several hydroelectric power plants, subways, highways etc., including major underground works (since 1990). He has also acted as consultant.
Professor Celestino continues to contribute his knowledge for the graduate courses & research areas on Rock Mechanics & Underground Works, at the São Carlos Engineering School, University of São Paulo and for the ITACET Foundation.
Our destination is the exploitation galleys of one of the largest underground mines of Attica. The chambers of metal extraction, rich in recognisable minerals, combine the mystery of ancient drifts with the beauty of caves. We will wander underground for up to 3 hours and explore the maize of drifts, the chambers supported by natural as well as carved-out pillars and the stalactites decoration reminiscent of natural caves. Each of the routes we follow hides surprises waiting to be discovered!
After we will visit the great “Chaos” sinkhole, a heart-shaped sinkhole formation 150m in diameter and 55m deep. This chiasm may have been formed by the collapse of a cave roof as many of the area’s mining tunnels end there.
Scientific theme: Underground mining activity in Lavrio
Duration: 6 hours inclusive
Detailed program
9.30-10.30 Athens-Lavrio
10.30-13.30 Underground mines
14.00-14.30 Stop at dolin “Chaos” and return to Athens
14.30 – 15.30 Lavrio-Athens
Cost per person: 40,00 €
*limited participation on a first come first served basis. In case participants are less than 20, the respective event will be cancelled and a refund wil be given.
How many surprises can the Athens underground have in store for its visitors? The stroll will start from underground shelters and detention areas of the German Kommandatur, remnants of the 2nd World War in Athens. Then, we will take the steps that start off under a timeworn trap door on the side of a road or hidden away in a sidewalk flower–bed, that will lead us in a different, forgotten underground area of the city! For hundreds of years, underground pathways have been used for various and mysterious purposes. Some say that all underground pathways are interconnected although there is no proof of this. Nevertheless, the allure of an unknown world is always there, beneath the ground we walk on. We lift up the antiquated hatch and descend the stone steps. In the catacomb, we come across tunnels of ancient aqueducts, roman baths and byzantine crypts. The Athens river is also found hidden below the ground, running in old galleys under the most central streets of Athens – we can hear the cars passing over our heads!
We invite you to discover together the hidden secrets of our city!
