Origin and history

Saint-Aignan Church, located in Senlis, Oise, was one of the seven medieval parishes in the city. Founded probably before the last quarter of the 11th century, it is distinguished by its Romanesque bell tower, model for other churches in the region such as Saint-Pierre de Senlis or Saint-Gervais de Pontpoint. This bell tower, with its bays decorated with billets and boudins modillons, bears witness to primitive Romanesque architecture. The building, initially symmetrical with two bell towers, was profoundly redesigned in the 13th, 15th and 16th centuries, incorporating Gothic elements such as a vaulted choir and a Tudor-style northern portal.

In the 16th century, the church adopted its definitive plan, including a flat-bed choir, side chapels and a sacristy. Four chapels founded by local notables (Notre-Dame, Saint-Jean-Baptiste, Saint-Nicolas, Saint-Charles-Borromée) underline its prosperity. The Revolution marked a turning point: sold as a national good in 1792, it became a sheepfold and then a theatre in 1814 under the impulse of Pierre-Jacques Fricaut. The nave was demolished in 1806 to build a classical facade, while the bell tower and chapels were preserved. The theatre, with coffee and dressing rooms, operated until the 19th century before becoming a cinema in the 20th century.

Ranked a Historic Monument in 1981, the church was restored in the 1980s by M. and Mme Raynal-Menes, who preserved its 19th century layout while revealing medieval elements as an unknown triforium. Today, it is abandoned and closed for reasons of security, and retains traces of its many lives: Romanesque vestige, Gothic transformations, and secular reuse. Its bell tower, symbol of regional architectural influence, and its chapels recall its central role in Senlis' religious and social life.

The building also illustrates the challenges of heritage conservation: after archaeological excavations in 1988 and a brief cultural renaissance as "space Saint-Aignan", it is now inaccessible. Its history reflects urban and cultural changes, from medieval times to modernity, revolutionary upheavals and theatrical adaptations.

Architecturally, the church combines Romanesque elements (closing with columnettes and modillons), Gothics (watermarked bays, ogival vaults) and classics (nineteenth century facade). The northern side chapel, with its quadrilobed lancettes and roses, and the Tudor portal decorated with gargoyles, testify to this superimposition of styles. Inside, the restorations of the 1980s highlighted this composite heritage, while maintaining the traces of its theatrical use, such as the stage platform and the stairs of the lodges.
