Author 'Boucher Marc dit de Meilh' (Id 194222 ) : On the shores of Loudon, along the water courses in the middle of the month of May... The Loudon, a small river that runs through Bourgoin-Jallieu, overflowed in the spring capricious. I saw the shot in the water out of the bed, the reflection of the castle of Rosiere was in it... The castle is quite far away yet, and the mirror effect is really miraculous ! Ph : Marc de Meilhan Butcher.
