The tour is extremely interesting, especially to see wood burning under solar energy, the guide was very professional and seemed genuinely passionate about the uses of solar energy, very good explanation altogether. The tour is in French only, but for us this wasnt a problem.

The furnace is located in one of the defensive bastions next to the one which provides entry to the fort. Dating back to the mid twentieth century and was probably the first of its kind in the world. Sunlight is collected and focused through a system of mirrors to concentrate it for various uses.

It is especially relevant in this era of pollution and global warming and definitely worth a visit if you are in the area.

This attraction is essentially a home-made solar furnace, where they use solely the power of the sun, focused through mirrors to fire pottery, burn wood (demo) and melt metal, achieving 3000 degrees C as temperatures.

As a feat, this is pretty impressive. The guided tour was French only and as such a little limiting and did go on a bit, but it was nevertheless very interesting.

The trip starts with a short video explaining the site and the activities. We were then taken outside, the main attraction is a large wall of mirrors which track the sun and reflect its light onto a large curve mirror which in turn focuses this onto a very powerful beam. We had various demonstrations (in French - it did not matter to me as the key was to see the demonstrations) including being shown the power of the sun with a smaller scale mirror which made wood smolder and then catch fire, also a small oven heated just by the sun. The most amazing demonstration was with the main mirror, which included a plank of wood bursting into brilliant flame as it was passed through the beam. We also saw large plates of metal which had been melted with the beam but for me the most amazing was the hole burned through a piece of slate where the slate had melted! If you are in the area it is well worth a visit as there are very few places in the world where you can experience this.
