3 heroic reasons to take the plunge!

Travelling through the galaxy

Who hasn’t dreamt of walking on the Moon, observing Saturn’s rings or crossing the Milky Way?

Disconnect from everyday life

For 1? hours, leave Earth behind. The immersive projection and soundscape will take you on a timeless journey.

An adventure for all the family

Whether you’re curious, a dreamer or an astronomy enthusiast, there’s a place for everyone to explore the sky and share a moment of discovery with the whole family.

Your adventure in detail

Take-off imminent!

Welcome to La Chapelle-aux-Lys (Terval), a discreet village in the Vendée bocage in the Land of Stars, which hides an unexpected treasure: the smallest village in the world to have its own planetarium. Here, the stars are more than just a night-time backdrop. They are an invitation to look up, slow down and explore.

Before take-off, the atmosphere is already there. It only takes a few minutes to realise that you are entering a place apart, where people talk about galaxies, constellations and infinity. In the planetarium room, you take a seat under the dome. The lights go down, silence falls… The countdown begins.

3… 2… 1… Lift-off. Your space mission can begin!

A journey through the galaxy

Under the vaulted ceiling of the planetarium, the sky comes alive and the adventure begins. Guided by an immersive projection and explanations from Olivier Sauzereau (or another member of the Astrolys association), you set off on a veritable exploration of the cosmos.

The starry night appears, revealing its constellations and its stories. Little by little, the journey expands: the planets of the solar system are revealed, the Moon comes closer, Saturn’s rings stretch out into space and the Milky Way unfolds its billions of stars.

The planetarium lets you change scale in a matter of seconds. You go from the sky visible to the naked eye to the farthest reaches of the observable universe. This celestial expedition combines wonder and understanding: you learn to recognise the stars, locate the planets and better understand the immensity that surrounds us.

When the lights come back on, one thing is certain: your view of the sky will never be quite the same.

Back on Earth… but still with your head in the stars

The adventure doesn’t end with the screening. As you leave the auditorium, take the time to discover the small interpretation area set up in the Planetarium.

Headphones are available to listen to content that will extend your discovery and give you a better understanding of certain astronomical phenomena. A little further on, a Camera Obscura invites you to observe the church using a device that is as simple as it is fascinating.

Extending the mission throughout the village

At La Chapelle-aux-Lys, astronomy is not confined to the planetarium. The whole village seems to be turned towards the stars.

Start by pushing open the door of Major Tom’s café des astres, a friendly place where astronomy enthusiasts like to meet up. On the walls of the café, an “astronomical” fresco immediately catches the eye and reminds us that exploring the universe is part of the identity of the place.

If you want to go further, take the ‘ Chemin aux Étoiles‘, an open-air educational trail that allows you to understand the universe as you walk. Along the way, astronomical distances take shape and the immensity of the cosmos becomes more tangible.

Enthusiasts can also take part in the courses and observations offered atOlivier Sauzereau‘s observatory, another gateway to learning how to read the sky.

And every summer, the village becomes the setting for a unique event: the Astrolys festival, a not-to-be-missed rendezvous for the curious and star-lovers.

Your guide, your ally

Without him, the magic won’t work!

  • A great time with Tom ★★★★★

    I had a wonderful time with Tom, who was very friendly and educational with young and old alike. It was a pleasure to discover or rediscover the mysteries of our universe. It was also an opportunity to remind ourselves just how infinitely small humans really are. It’s easy to book, just a few clicks away, and don’t forget to bring a few tickets for the sock that serves as a hat (as it’s free). The association deserves it.

  • A small village but an extraordinary site ★★★★★

    It’s a small village, but an extraordinary site managed by a dynamic association that has made it a must-see for all enthusiasts, whether novices or enthusiasts, of the starry sky, our universe and far beyond! Olivier is a passionate and fascinating guide who will take you on a journey from our solar system to the very edge of it, far, far away, further and further away, from which you will emerge with stars in your eyes, a smile on your face, a wealth of new knowledge, different and happy to have been part of the crew. Without doubt, a privileged experience. All with a lot of listening and humour. Thank you 🤩 so much. Olivier, I’ll swap a calva for a troussepinette. Because after hearing so much about it, I’d really like to try it 👅

Good advice from the Tourist Office!

Anticipate your take-off

Sessions often sell out (12 people max.). Book in advance to make sure you’re part of the crew and don’t miss your space trip.

Switch off your terrestrial connections

To take full advantage of the immersion, put your phone on silent and leave everyday life behind. Here, you really pick up the phone… for a better journey.

Extend the experience in the village

Don’t stop at the planetarium. Take the time to wander along the Chemin aux Étoiles and discover the other facilities in the village to fully experience your mission (sundials, outdoor exhibition, fresco on the façade of Major Tom’s café, etc.).

Prepare your mission!

Other adventures await you…
