Nice Sunday morning Gravel ride. Arrived at 8 am in Miribel park, not a soul 🐈⬛ but a few hares and signs waking up quietly near the many beaches. I'm surprised by the quality of the singles and trails which are super well maintained. Would gladly do it again.

The Bienassis fortified house, built by the Vallin family at the end of the 14th century, was organized around an enclosed courtyard and included a pavilion surrounded by watchtower turrets. The current building was completed in 1897 for Casimir Gournet, who wanted to give the old feudal residence the appearance of a medieval castle. Alphonse de Lamartine made several stays in Bienassis with his friend Nicolas Prosper Guichard, between 1804 and 1808. The castle, built of limestone rubble, consists of an L-shaped building covered with a long-pitched roof covered with mechanical tiles extended to the south by a high quadrangular tower with a porch in the work. The north wing has four levels of elevation: three cellars on the basement floor, a square floor and an attic floor. The tower rises on three levels: a ground floor with ribbed vaults and two square floors, the buildings are crowned with false machicolation. The corner turrets are covered with conical slate roofs. The stained glass windows of the ground floor living room are decorated with two bust-length women and two bust-length men in rondels. The coat of arms of the Joubert de Montlevon family can be found on one of the windows of the first living room on the ground floor. In the library, two shields with scrolling scroll motifs, a shield decorated with three female heads, a shield decorated with a passing griffin, and a shield decorated with two hammers with the initials C G for Casimir Gournet adorn the windows.

Flat bike path along the reservoir. Unfortunately, the scenery is a bit boring.
