"The legacy of George Sand is celebrated every year, at the International Meetings of luthiers and masters ringers; Since 2009, they take place in the castle of Ars, in the neighboring town of Lourouer-Saint-Laurent). It is the biggest European event devoted to ancient and traditional music and instrument factors, and the first manifestation of the department of Indre. The castle was bought back in 2008. Since then, extensive restoration work has continued15.

"In 1992, the Alsatian poet-troubadour René Egles devoted one of his works to the atmosphere that emerges from these "Rencontres internationales" through the title "La Chouette de Saint Chartier". He explains it himself: "Saint-Chartier is the Mecca of the folk of France, with a throne reach of Nohant, where George Sand, the good lady of the place, resided! When the floodlights and the songs of the bagpipers, Celtic hurdy-gurdy harps and Celtic harps are lit in the dark night of Saint-Chartier, the owl of the castle unfurls its white wings and hangs over the festival. It is this atmosphere that I tried to recreate on my zither"

One of the organisers is an Irish guy living in France, mentioned
