Martyrium of Saint Denis, Montmartre, crypt located in Paris, in France
The Martyrium of Saint Denis in Montmartre is a small underground chapel beneath the streets of Paris's historic district. The site consists of a plain stone building with simple decorations, housing a crypt below ground that contains an old altar and artistic works from the Middle Ages.
The site was founded around the year 475 when residents of Paris built a small chapel to honor Saint Denis, the first bishop executed for his faith. The location was destroyed during the French Revolution but was rebuilt between 1884 and 1887, serving since then as a reminder of early church history.
The crypt is connected to Saint Denis, the first bishop of Paris, whose story is tied to the faith of early Christians in France. Visitors today use the space for prayer and reflection, connecting with the religious past of the city.
The site is located in Montmartre, an easily accessible neighborhood with narrow streets that you can explore on foot and that sits near museums and other historical sites. The crypt is small and contained, making a brief visit ideal for enjoying the space without rush.
The site is connected to a significant religious event: in 1534, important Christian figures made a vow here that led to the founding of the Jesuit movement. This event made the place a turning point in European Reformation history.
