The first stone of the Saint-Rémy church was laid by Thomas Bouchard, alderman and treasurer of the city, in 1522. However, its construction lasted more than 100 years and was completed in 1643. The work was interrupted for several decades because of the conflicts of the Wars of Religion opposing Catholicism and Protestantism.
The Saint-Rémy church illustrates the establishment of the Counter-Reformation movement in Dieppe. Indeed, faced with the influence of Protestantism which aimed for a sobriety of worship, the Catholic power aimed to attract and control the faithful.
In the 17th century, a baroque altarpiece was built which helped to establish a sensitive relationship with the sacred, visible in the chapel of the Virgin.
In the 18th century, the Parisot organ exalts the prayers of the parishioners.
Listed as a Historic Monument in 1910, the Saint-Rémy church underwent a series of restorations from the 19th century.
Since 1990, several restoration campaigns have been undertaken. In 2022, the black ambulatory was inaugurated after more than a year of work. The interior and exterior have been reconstructed, including gargoyles sculpted by Morgan Roulland.
