On one of the high points of the hill of L'Isle d'Abeau, on the northern edge overlooking the hamlet of Didier and the quarries, is the location of the old fortified house of the Pollouds, a family mentioned in the 14th and 16th centuries. centuries. The Napoleonic land register shows that several buildings were still standing in the first half of the 19th century under the name of “Delay” castle (name of the farmer who bought the land after the Revolution). The chapel, circular in plan, occupies one of the towers of the old castle, as shown by the presence of three keyhole shooting slots. In the 1860s, the owner transformed this tower, then serving as a henhouse, into a public oratory, which he had decorated with a mural and a statuette of Saint Anne.

Rosière Pond NATURAL HERITAGE Rosière Pond BACK TO THE LIST Rosière Pond© Martial-Couderette The Rosière pond is located to the north-east of the town of Bourgoin-Jallieu on the edge of the town of Ruy-Montceau and offers an ideal relaxing setting. The association “Les Amis de Rosière et de la Nature” manages the pond made available by the city. The Rosière pond, fed by the Loudon stream, was built in the 18th century to power a hemp mill (the current restaurant). This pond was the property of the GENIN family for a long time before being bought by the town of Bourgoin-Jallieu in 1978. Since then, the town of Bourgoin-Jallieu has done everything possible to make this site a protected natural place, walks and hikes and a fishing spot. Many hiking trails start from the pond.
