In the morning we were taken into the souterrains, des sources du Limancon - a series of underground tunnels and reservoirs that were excavated beneath St. Avertin long ago to bring water to the fountains of Tours.  From there we went to the town's cultural center at Chateau Cange where our guides took us to the glacier or ice storage cave that was hewn deep in the cliffside.




In the afternoon the host families took us all to Chateau Chenonceau, a magnificent castle set upon the Loire river.
