② The « Pique-Nique Electrique » is a strong hallmark of Explora because of its atypical, fun and educational facilities. Positioned near the ExploraLab, it allows the public to immerse themselves in the theme of energy thanks to several interactive modules where movements activate an electricity generator. Swings, Lumijump, bikes and seesaws create a sound and light atmosphere on the site. The public is thus invited to cooperate and exchange to create together a unique sensitive atmosphere.

③ The « Zone Defi » gives scope to the public’s ideas and puts them into action in an environment that encourages creativity and ambition. A platform is set up with springboards, markings on the ground, height brackets, vertical plans in order to be able to test the constructions made in the ExploraLab without space constraints. Here, cars jump over obstacles, dragsters take off as far as possible, rockets take off brilliantly and parachutes gain height.

④ The « Jardin de la Recherche » is an open space, made up of four areas in which research teams from Jean Monnet University, IUT Saint-Étienne and Mines Saint-Étienne are carrying out studies related to plants.
This garden is both a place for general public walks and a site designed and imagined for research. Researchers and students use the squares to study the role of plants in soil remediation and the use of different plants by pollinating insects.

⑤ The « Zone Sonore » thinks big and resonates within the park thanks to surprising installations. Two giant parables face to face, instruments at human height, a forest of voice tubes, a piano on the floor … all to exercise our listening skills and have fun with sound waves. These installations form a space that stimulates the appropriation of the park by passers-by and brings together people of all ages and from all backgrounds around games on sounds, voices and music.

⑥ The « Jardin du Carbonifère » pays homage to the history of plants, on the trail of the lost Saint-Etienne landscape. Ferns, horsetails, conifers and arborescent Lycocphytes, current close relatives of the Carboniferous flora 300 million years ago, form a garden that echoes the fossil flora whose traces have been found in the subsoil of the region . This station is built around monumental plant sculptures inspired by horsetail, a remarkable form of the Stephanian. It is an evocation of the grandeur of the flora of the Carboniferous period, which invites us to consider the impact of the passage of time and the evolution of our environment with modesty and reverie.

⑦ The « Balade dans l’Évolution » allows the public to physically experience the evolution of living things and the Earth in different geological ages. It also helps lay the groundwork for the development of techniques from the creation of the first tools 2.7 million years ago to today.

Take a walk and discover the 29 colored tiles scattered around ExploraParc!
By simulating 1 million years = 1 meter, it is a formidable tool for mediation and representation. In order to be able to humbly consider our place as human beings in this evolution.

Maker and STEAM

Explora is particularly inspired by the Maker movement, which has been developing in the United States since the 2000s. This culture of DIY (Do It Yourself) encourages people to rediscover the pleasure of imagining, creating and manufacturing oneself, using both artisanal techniques and new technologies. Importance is given to sharing and collaboration, open source culture and exchanges between participants.

Explora is at the frontier of Science, Technology, Engineering, Art and Design. In this sense, the culture of the place is similar to STEAM (Science, Technology, Engineering, Art and Mathematics) educational practices, which seek to develop critical thinking and so-called soft-skills.

Explora is the place to imagine, craft and play !
Here, we MAKE science !

Who we are ?

A place of science

Explora is a scientific and cultural establishment of the City of Saint-Étienne, managed by La Rotonde, Center for Scientific, Technical and Industrial Culture of École Nationale Supérieure des Mines de Saint-Étienne.

For more than 20 years, La Rotonde has taken you on a journey of scientific adventures. It now has two locations : La Soucoupe and Explora, and also offers multiple actions outside the walls and in digital.
