4. Troussures-Auneuil to Cauvigny

It is from the end of the 18th century and the beginning of the 19th century that Auneuil was to become part of the industrial world. First the brickworks develop, then it will be the tile and ceramic industry which will radically change the face of Auneuil.
A pause in this development will be observed during the war of 1870. Auneuil was then occupied by a cavalry squadron of the Prussian army. When peace returned, the industries started again and will take their full development with the arrival of the railroad in 1875. Auneuil is then connected to Beauvais and Gisors.
Ceramics was one of the traditional productions of Auneuil thanks to the brothers Aimé and Achille Boulenger who will manufacture architectural ceramics, in competition with the Colozier tiles of Beauvais, during all the XIXth century from a small workshop bought in 1848. Museum of ceramics patron's house that the last Boulenger brother bequeathed to the commune on his death in 1900.

The church of Saint-Germain dates from the 14th century and was built with the help of the abbey of Saint-Paul, founded by Angadrème in the 7th century and venerated in Beauvais, for the choir. The lords of Berneuil took charge of the nave and the bell tower. It overlooks a charming square decorated with an old playground, a watering hole, a well restored wash-house, and a remarkable tree, a black Italian poplar, 36m high and 100 years old.

The commune is dominated by larris, the limestone grasslands that were once used for grazing herds. It is one of the last large areas of this nature in the region.
The church of Saint-Denis as we can see it now is the result of transformations, adaptations and amputations. Thus, in the 16th century, the apse, which threatened to collapse, was demolished. The choir was reduced in length and closed by a wall with a large ogival window overlooking the high altar. In place of the apse, a sacristy was built.
