A tourist attraction in this area is Lake Paladru, which stretches from the village of the same name in the north to Charavines in the south. If you walk around the lake from a distance rather than on the paths directly along the shore, the hills offer some very beautiful views of the landscape. But not only that: on the outskirts of Bilieu – on the eastern shore of the lake – we pass a small sacred monument: a simple wayside cross made of two massive wooden beams (without a body or INRI inscription), which already shows the wear and tear of wind and weather.

Here we encounter three stone cubes stacked on top of each other, each smaller than the one below it. The gray cubes each have a white field in the center of their sides, with a cross carved into it, painted blue and standing out against the gray/white background. This construction forms the basis for the present small sacred monument: above it rises a radiant gold figure of the Madonna. From this prominent position, the Virgin Mary – venerated in France almost always under the title "Notre-Dame" ("Our Lady") – gazes far into the country, and has done so for more than 120 years. @Rainer N. has already explained the date and reason for its construction in his short post.

Located at an altitude of 500 m at the bottom of a depression of glacial origin with a substantially north-south axis, the Etang du Grand-Lemps nature reserve presents an exceptional flora and fauna heritage over 53 ha. Its slopes are shared between pastured meadows, crops and chestnut copses. The bottom of the depression corresponds to a marsh covered by peat bog vegetation and phragmites. The peat environments, and more particularly the sphagnum groups, constitute the originality of the site. Source: Natural Reserves Org

With its views and its picnic table, this place is an ideal place to pass. The statue was erected in 1903 to protect the vines against the phylloxera virus which devastated so many winegrowers.
