Located on the borders of Valois and Picardy, this town of about 2200 souls and 470 hectares, bordering Compiegne, however retains a certain rural character. The village stretches at the foot of a hill at 155 m altitude, Mount Ganelon. A peaceful river, the Aronde, crosses Clairoix, and the confluence of the Oise and Aisne is at the limit. The Paris-Maubeuge railway line, and two main roads, the national 31 and the former national 32, border the oldest part of the village.
Historically, Mount Ganelon has always been of great importance to Clairoix, who has exploited its lands, springs, vineyards, quarries, woods, etc. ; and it is undoubtedly the strategic position of this mound, near the confluence of two great rivers, which is at the origin of the creation of the village.
The Aronde, meanwhile, has long rotated five water mills, associated with important buildings gradually become, in the twentieth century, beautiful private properties.
Among the other notable buildings of Clairoix are the church, the "villa Sibien", the property of Comminges (leisure center of the RATP), and the Clos de l'Aronde, the current town hall, which sheltered some illustrious families like those of Hervé de Tocqueville, Joseph Pinchon (draftsman of Bécassine), or Louis Duval-Arnould.
Until recent decades, Clairoix has been a predominantly agricultural (and viticultural) commune. Apart from flour mills and brick factories, few production companies established themselves there before the 20th century. The most important industrial site of the municipality was the tire factory Englebert-Uniroyal-Continental, which followed an ephemeral artificial silk spinning, and which ceased its activities in 2009.
Currently, the village has a residential vocation, and benefits both from the proximity of the city of Compiègne, easy access to various roads, a pleasant natural environment, quality equipment, and a communal and dynamic community life.
