Basilique Saint-Denys d'Argenteuil

The basilica is a church building with neo-Romanesque architecture, marked by a triple monumental porch and a 57-meter bell tower designed by Théodore Ballu. The interior contains two separate organs and restored stained glass windows from the 1950s.

This church replaced an older parish church from 1449 and was consecrated in 1866, then elevated to basilica status in 1898. The reconstruction took place during an era when churches still held central places in public life.

The basilica houses the Holy Tunic, a garment traditionally linked to Christ's Passion that is displayed during special ceremonies every 50 years. Visitors can sense the spiritual significance of this relic for pilgrims and worshippers who gather here.

The basilica is located near Argenteuil's historical center and is easy to reach on foot. Visitors should note that access times may vary and it is wise to check ahead before planning a visit.

The pediment displays 'Freedom - Equality - Brotherhood', inscribed before the 1905 separation of church and state in France. This rare feature shows how secular ideals were reflected in the architecture of religious buildings at that time.
