The 150th Jubilee of the first apparition took place on 11 February 2008 with an outdoor Mass attended by approximately 45,000 pilgrims.
Today Lourdes has a population of around 15,000, but it is able to take in some 5,000,000 pilgrims and tourists every season. With about 270 hotels, Lourdes has the second greatest number of hotels per square kilometre in France after Paris. Some of the deluxe hotels like Grand Hotel Moderne, Hotel Grand de la Grotte, Hotel St. Etienne, Hotel Majestic and Hotel Roissy are located here.
In the evening of February 11, 1858, a young Roman Catholic girl, Bernadette, went to fetch some firewood with her sister and another companion when a Lady who was indescribably beautiful appeared to her at the Massabielle grotto. Although the Lady did not tell Bernadette her name when asked at first, she told her to return to the grotto. On subsequent visits, the Lady revealed herself to be the "Immaculate Conception". This was a reference to the dogma of the Immaculate Conception which had been defined only four years earlier in 1854 by Pope Pius IX, stating that the Virgin Mary herself had been conceived without sin. Bernadette, having only a rudimentary knowledge of the Catholic faith, did not understand what this meant but she reported it to her parish priest, Father Peyremale. He, though initially very skeptical of Bernadette's claims, became convinced when he heard this because he knew the young girl had no knowledge of the doctrine. The Lady also told Bernadette to dig in the ground at a certain spot and to drink from the small spring of water that began to bubble up. Almost immediately cures were reported from drinking the water. And yet the water has been shown through repeated testing to not have any special curative properties. Today thousand of gallons of water gush from the source of the spring, and pilgrims are able to bathe in it. Countless purported miracle cures have been documented there, from the healing of nervous disorders and cancers to cases of paralysis and even of blindness. "The estimate that about 4000 cures have been obtained at Lourdes within the first fifty years of the pilgrimage is undoubtedly considerably less than the actual number." During the Apparitions, Bernadette Soubirous prayed the Rosary. Pope John Paul II wrote: "The Rosary of the Virgin Mary is a prayer with great significance, destinated to bring fruits of holiness".
Lourdes is located in southern France in the foothills of the Pyrenees mountains near the prime meridian. It is overlooked from the south by the Pyrenean peaks of Aneto, Montaigu, and Vignemale (3,298 m), while around the town there are three summits reaching up to 1,000 m (3,280.84 ft) which are known as the Béout, the Petit Jer (with its three crosses) and the Grand Jer (with its single cross) which overlook the town. The Grand Jer is accessible via the funicular railway of the Pic du Jer. The Béout was once accessible by cable car, although this has fallen into disrepair. A pavilion is still visible on the summit.
Lourdes lies at an elevation of 420 m (1,380 ft) and in a central position through which runs the fast-flowing river Gave de Pau from the south coming from its source at Gavarnie, into which flow several smaller rivers from Barèges and Cauterets. The Gave then branches off to the west towards the Béarn, running past the banks of the Grotto and on downstream to Pau and then Biarritz.
On land bordered by a loop of the Gave de Pau is an outcrop of rock called Massabielle (from masse vieille: "old mass"). On the northern aspect of this rock, near the riverbank, is a naturally occurring, irregularly shaped shallow cave or grotto, in which the apparitions of 1858 took place.
