Listed as a Historic Monument, the Notre-Dame church is a very interesting building that expresses some very characteristic features of the architecture of the Norman School, particularly in the Gothic choir attributed to the 13th century. The bell tower-porch has a late 15th century portal with an ogival arcade that frames an openwork tympanum. Above the portal is built a flamboyant style rose window. The nave, flanked by two side aisles, was built in the 13th century, but was extensively remodeled in the 16th and 17th centuries. It has an interior elevation on 3 levels. All that remains of the primitive Romanesque church is the base of the old lantern tower. Visible only from the outside, it is located at the crossing of the transept. The church has some singularities: -The sepulchre dating from the 15th century, representing Christ stretched out on a shroud, Nicodemus, Joseph of Arimathea, Saint John the Evangelist, the Virgin Mary and Mary Magdalene. -The stained glass windows are attributed for the most part to Édouard Didron, a great Parisian master glassmaker.

This natural area located in Forges-les-Eaux is organized around the ponds of the Andelle, formed by two rivers: the Andelle to the east and the Chevrette to the west. All around extends the Bois de l’Épinay, remarkable for the great diversity of tree species it shelters. You can walk there, observe the birds, picnic and take a quiet break enjoying the rustling of the many leaves.

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.

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

The Fontaine aux Dames wash house, purchased by the town hall in 1998, has undergone a complete restoration. The original building being in ruins, a reconstruction was carried out according to a Brayon washhouse model in the year 2000: low brick wall, oak frame and roofing in traditional local tiles. The wash house houses a ceramic work “the monument to the unknown lover” which we owe to the Brayon artists Jacques and Juliette Damville; This monument pays tribute to women for the role they played during the First World War.
