No act of devotion at Lourdes is more universal than lighting a candle. From the earliest years after the apparitions, pilgrims have brought candles to the Grotto as a physical expression of prayer — the flame representing a petition, a thanksgiving, an intercession for someone who could not travel. Today, the Lourdes Sanctuary burns approximately 750 tonnes of candles annually, making it one of the largest votive candle traditions in the world. Understanding the meaning of this simple act transforms it from a tourist activity into one of the most intimate moments of a pilgrimage.

The Tradition's Origins

Candle offerings at the Grotto began within months of the 1858 apparitions, when early pilgrims spontaneously brought candles to mark the site of Bernadette's visions. By the 1860s, the practice had become so widespread that the Sanctuary established dedicated candle stands near the Grotto to manage it safely. The tradition has continued without interruption for over 160 years. The candles burned at the Grotto are not produced commercially elsewhere and then sold as Lourdes candles: they are manufactured to the Sanctuary's own specification from natural wax and are among the purest votive candles produced in Europe.

Choosing Your Candle

Candles are available at stalls near the Grotto in a range of sizes from small (approximately 50 centimetres) to large (over two metres tall). The size you choose is a matter of personal preference and budget: small candles cost approximately €1–€3, medium €5–€15, large €20–€50 or more. Larger candles burn longer and are often chosen by pilgrims who wish to maintain a flame over a longer period, or by groups offering a shared candle on behalf of a parish community. Many pilgrims choose a candle that matches the scale of what they are bringing to the Grotto: an everyday intention might call for a small candle; a serious illness or a significant need, something larger.

Inscribing a Name and Lighting the Candle

Most candle stalls provide markers or labels for inscribing a name or intention on your candle. This is not required but is a meaningful addition: naming the person or need for whom the candle burns makes the offering concrete and personal. The candle stands themselves are arranged in rows near the Grotto cave. You light your candle from one of the existing flames (a lighter is provided near the stands), place it in a holder, and offer your prayer. There is no prescribed formula — simply speak to God and to Our Lady in your own words. Many pilgrims stand for several minutes in silence; others kneel. All of it is prayer.

The Best Time to Visit the Candle Stands

The candle stands are beautiful at any hour, but most magnificent at dusk, in the dark of night, and in the still of early morning. At night, the accumulated glow of hundreds of candles turns the stone of the Grotto warm gold, creating an atmosphere of extraordinary luminous peace. In the early morning, before the crowds arrive, standing alone before the quietly burning flames is one of the most intimate experiences the Sanctuary offers. The combined glow of thousands of flames, each representing a human intention placed in God's hands, has a quality that even the most secular visitor tends to find affecting.

The Theology of the Offering and Taking Candles Home

The votive candle embodies a theology of offering: giving something of oneself — time, money, attention — as a material expression of an interior prayer. The flame represents both the prayer itself and the ongoing intercession that continues after the pilgrim has left the Grotto. Many pilgrims purchase additional candles to bring home as gifts for family members, the sick, or those who asked to be remembered at Lourdes. Unlit Lourdes candles make deeply meaningful gifts — not as souvenirs but as a continuation of the Grotto's prayer brought into someone's home. A candle lit at home for a sick friend, using a Lourdes candle brought back from the Grotto, carries the intention in both directions.
