Nolay with your eyes peeled !

It is a proposal of free visit or accompanied with your eyes peeled and to find details that we would not see otherwise! Find small wonders and always ecstatic or try to understand, what could be the use of this hook, what is the use of the rings located on the facades or the stones planted around the halls… and begin to elucidate all sorts of hypotheses. If you want to see more clearly, make this visit the Nose in the Air with a local guide!
