Have fun with your family by visiting the troglodyte village of Trôo and downloading the 2 pages of "Amuz’Trôo" n°1 and 2, two photo questionnaires.... and a gift to win!
In the 2 game supports, you will discover 9 photos taken at various places in the village. On the second page of the document, you have a map of the village with 9 numbers corresponding to the places to find.
Children’s mission: it is to find the place on the map where each photo was taken. A letter identifies each place.
Parents' mission: it is to find for each photo, the word to discover thanks to the clues...
You wish to discover what a troglodytic village is while having fun, so Trôo is the ideal place! Its picturesque alleys and its countless stairs are real labyrinths... Before you borrow them and discover the entire excavated hillside, bring one of the 2 small photo questionnaires (downloadable here or you can also go pick it up at the reception of Trôo Tourisme). During this free visit you will have to find the place where each photo was taken and your parents will have to find the mystery words using clues... So who will succeed in their mission first: you or your parents?
To check the answers and take a surprise gift, quickly return to the reception of Trôo Tourisme and take the opportunity to visit the petrifying cave.

About the location

Grotte pétrifiante de Trôo

39 rue Auguste-Arnault 41800 Trôo

Loir-et-Cher

Centre-Val de Loire

It is the oldest tourist site in the village of Trôo. Already open to the public at the beginning of the 20th century, this small space, dedicated to the long work of calcareous waters, is interesting on a tourist level, of course, but also from a geological point of view. You can discover stalactites, the remains of the old chapel Saint-Gabriel, its petrified basin and all the magnificent work of water on tuff (local limestone) in 300 years. The cave has significant water resources; this water, coming from various sources whose exact origins are not known and which flows from the center of the Butte which is extremely loaded with limestone. The Loir valley was, 90 million years ago, a huge inland sea, hence the cavities that were dug throughout its bed.
Why is it petrifying? Water, loaded with carbon dioxide, dissolves the limestone of the rocks it passes through and, when it comes into contact with warmer air in cavities, deposits the transported calcite. It accumulates in stalactite
