Château-Gaillard is a French commune with 2,138 inhabitants (at January 1, 2017) in the department of Ain in the region Auvergne Rhône-Alpes . It belongs to the canton of Ambérieu-en-Bugey in the arrondissement of Belley and is a member of the Plaine de l'Ain community association .



Château-Gaillard is located at 240  m , about 26 km south-southeast of the prefecture of Bourg-en-Bresse , 38 km northwest of the city of Belley and 43 km northeast of the city of Lyon (as the crow flies). The village extends in the lower Ain Valley on the border between the Dombes landscape in the west and the Lower Bugey in the east. Neighboring communities of Château-Gaillard are Priay and Ambronay in the north, Ambérieu-en-Bugey in the east, Saint-Denis-en-Bugey and Leyment in the south, and Saint-Maurice-de-Rémens in the west.


The area of ​​the 16.06 km 2 municipal area comprises a section in the flat plain that the river Ain forms on its lower course. The valley floor, which is almost ten kilometers wide, is bordered on the other side of the municipal boundaries of Château-Gaillard by the Jura mountains in the east and the Dombes plateau in the west. The actual river bed is a few hundred meters west of the municipality, the western border of which runs in the alluvial forest of Les Brotteaux, which is crossed by oxbow lakes . This is followed by another two-kilometer-wide depression that is used for agriculture but is not built on. The actual settlement area begins east of a 15 meter high river terrace and forms several districts in an otherwise agriculturally used plain. The southern edge of the municipality is bounded by the Albarine , a left tributary of the Ain. The Le Seymard stream runs directly below the river terrace and also drains the communal soil . Correspondingly high is the agricultural share of the municipal area (69%), followed by industry and commerce (11%), wooded areas (9%) and housing (6%).

Community structure

In addition to the actual town center, Château-Gaillard also includes the village of Cormoz in the south and the settlement of La Poisatière on the municipal boundary with Ambérieu. In the north-east of the district there is a small industrial park, which is followed by an airfield. In the far north there is a gravel mine .


The area of ​​Château-Gaillard was already settled in pre-Roman times. Larger outlines of settlements and burial grounds were discovered, as well as small finds from the successive epochs of the Bronze Age , Hallstatt Age and Latène Age. From the Roman period , from which most of the finds have been preserved, the floor plans of a building complex were reconstructed, which developed from a local farm from the 1st century AD to a Roman villa, but which suddenly changed in the middle of the 4th century was abandoned.

In the feudal deeds of the Middle Ages, the place does not appear again until 1357 under the name Castrum Gaillardi , when it was under the suzerainty of Count Amadeus VI. von Savoy changed the feudal man several times. With the Treaty of Lyon in 1601, all of Bugey became part of France. The parish, first mentioned in 1655, was originally a deanery dependent on the Ambronay monastery and later became a branch of the parish of Ambérieu.

The castle complex, which gives the place its name, was built between 1345 and 1350 and, together with the castles of Saint-Denis and Saint-Germain (in Ambérieu), defended the entrances to the Ain Valley and the Cluse des Hôpitaux against the Dauphiné . It was burned down during the French Revolution and subsequently dismantled.

Economy and Infrastructure

Until well into the 20th century, Château-Gaillard was predominantly an agricultural village. Today this is concentrated on a few farms that cultivate large areas of grain as well as oil and protein crops. There are also a few smaller industrial companies that have settled at the motorway exit, and various local small businesses. In the meantime the village has also developed into a residential community. Many workers are commuters who work in Ambérieu or more distant surroundings, especially in the Aix-les-Bains and Chambéry area.

The place is well developed in terms of traffic. In the municipality there is a connection to the toll motorway A42 (part of the direct connections Lyon-Geneva and Lyon-Strasbourg). In neighboring Ambérieu, the main roads D1075, D1084 and D1504 cross, which connect different urban centers in the Rhône-Alpes region. A station served by the TER Rhône-Alpes is also located in Ambérieu, through which the two lines Lyon – Geneva and Mâcon – Ambérieu run. The airports in the region are Lyon-St-Exupéry (46 km) and Geneva (103 km).


In Château-Gaillard there is a state école primaire (elementary school with an integrated preschool ).
