This majestic facade located near the Casino comes from the town of Gisors. Originally, it was the facade of the chapel of the Carmelite convent built in the 17th century at the initiative of François Sublet. After the French Revolution, this building was transformed into a municipal theater before being bombed during the Second World War. Jacques Hébertot, owner of the Forges Casino in the 1950s, bought the last remaining intact vestige from the town of Gisors and erected it in the town of Forges-les-Eaux with the aim of recreating a certain historical setting.

This area is located just at the entrance to the Andelle ponds, opposite the casino. A few tables are available, at the foot of the lake, for a nice picnic. Be careful, places will be expensive on a nice day!

A path has been laid out to reach the sources of the Chevrette: footbridges and pontoons, winding paths, the undulating presence of the Chevrette which plays with the path by shimmering its strange ocher color... We let ourselves be invaded by this beautiful atmosphere in the undergrowth to the source itself.

This part of the city was developed from the 16th century with the discovery of ferruginous springs in the current Casino park. It was in 1573 that Nicolas de Moy, Grand Master of Water and Forestry, discovered the presence of ferruginous springs. They were made famous from 1633 with the arrival of King Louis XIII, Queen Anne of Austria and Cardinal Richelieu. The spa was thus born! The springs named Reinette, Royale and Cardinal were thus exploited for their property and their medicinal virtues until the 1980s. @OT Forges les Eaux

These artificial lakes were built in the late 1980s on a peat marsh. They are spread over two levels and separated by an earth dike, valves allow the water level to be controlled. They are fed by the Andelle river which has its source upstream. The wild ponds (to the North) were deliberately left in their natural state to allow birds to nest, while The Bird Mirror (to the South) was the subject of landscaping and ornamental development with consolidation of the banks. . @OT Forges les Eaux
