Rieg has been the boss for the three years that we have volunteered at Chateau D'Urfé.
He is a master mason, a good teacher, and very much of an acrobat.
Below he perches on the edge of a wall that is 20 meters above the ground.
Above Rieg gives pointers to a young mason.
Below, Rieg carries mortar made with limestone and sand up to the scaffolding where two volunteers are rebuilding a wall.
