Completely constructed in white and black stone, the Basilica of Saint-Quentin is the second Gothic building in Picardy. Built between the end of the 12th and the end of the 15th centuries, it is best known as the burial place of the martyr Quentin, who gave it its name.
Listed as a historical monument, the building boasts original architecture, with a porch tower over 34 meters high, a double transept, and a concentric choir.
Inside, visitors are captivated by the ancient 260-meter-long labyrinth carved into the nave's paving. Stained glass windows installed at various times complement the artistic offerings of the Basilica of Saint-Quentin, particularly medieval stained glass windows in the 12th-century apse chapels. These depict episodes from the lives of the Virgin Mary and Saint Stephen.

Saint-Quentin war memorial

Highlight • Monument

The Saint-Quentin war memorial is a unique memorial dedicated to the city's soldiers who fell in combat during different wars. The monument is located near the train station and features a large granite wall with three bas-reliefs depicting scenes from 1557, 1870 and 1914-19181. You can admire the work of architect Paul Bigot and sculptors Henri Bouchard and Paul Landowski, who created this impressive structure in 1927. The monument is also a tribute to the resilience of the residents of Saint-Quentin, who endured the destruction and exodus caused by conflicts.
