This year again, a photography contest will be held for an exhibition during the congress.
The theme for your photos will be:
“A journey to the centre of the Earth, views of underground lines”
This contest is free and open to anyone who wishes to contribute to illustrating the adventure, fantasy and mystery of underground spaces.
To do so, take a fresh look at underground spaces, their architecture, the places where the underground emerges or enters the earth, construction sites as landscapes, underground stations as living spaces, and entrances to basements, both functional and welcoming. These urbanised or natural underground areas are places of transformation, passage and storage that are reinventing and rediscovering themselves as unknown spaces.
Pick up your cameras and enjoy the journey!
Registration for the photo competition is scheduled to open in early February 2026
