On the night of May 8, 1630, an ox-cart carrying two terracotta figures of the Virgin Mary came to a halt on the southern bank of the Luján River and refused to move. The carter, a slave named Manuel belonging to a estanciero named Rosendo Oramas, unloaded one figure and then the other, testing which one the oxen would accept. When the image of the Immaculate Conception was set aside, the animals stood firm. When it was placed back on the cart, they would not budge. By morning the message was unmistakable: this small figure, barely thirty-eight centimetres tall, had chosen her resting place. Four centuries later, the same spot draws more than two million pilgrims a year, making Luján the spiritual heartbeat of the Southern Hemisphere's largest Catholic nation.
The city that grew around this miracle sits on the flat Argentine pampa some sixty-eight kilometres west of Buenos Aires, where the sluggish Luján River once marked the frontier between colonial settlement and open grassland. Today the basilica's twin neo-Gothic spires — rising 106 metres against a sky of spectacular width — are visible from the highway long before the city itself comes into view. Pilgrims arriving in October often see the highway behind them solid with walkers for as far as the eye can reach: teenagers, grandmothers, veterans, families pushing prams, all converging on a church whose scale was designed from the beginning to receive a nation.
The devotion at Luján is not the refined piety of European shrines. It is something rawer and more democratic: a faith carried in blistered feet and cheap plastic ponchos, in the cumbia played from pickup trucks at the rest stops, in the improvised altars of flowers and photographs left at the basilica's iron fence. It belongs equally to the poor Black slave Manuel who guarded the statue alone for half a century and to Pope Francis, who made his own pilgrimage here as Archbishop of Buenos Aires in 2010, walking in the rain with hundreds of thousands of faithful. What began with a stubborn pair of oxen has become, in the words of the Argentine hierarchy, "the most concrete expression of popular Argentine Catholicism."
📜 History & Spiritual Significance
The statue's journey to Luján began in Brazil. António Farías de Sáa, a Portuguese landowner in Santiago del Estero, requested that two terracotta images be shipped from the workshops of Bahia — one of the Immaculate Conception, one of St. Francis — to furnish a private chapel he was building on his estate. The figures were packed into a cart in Buenos Aires in 1630 and sent north. When the cart stopped at the Luján River crossing and the oxen refused to move, the incident was recorded as a miracle and the image of the Immaculate Conception was left in the care of Rosendo Oramas.
The man who gave that image its first home in an act of selfless devotion was Manuel, a man born around 1604 in Cape Verde, brought to Brazil as an enslaved child, and eventually sold into the household of Captain Bernabé González Filiano near the Luján River. From the moment of the miracle, Manuel became the image's guardian — receiving pilgrims, offering water to travelers, and caring for the sick who came seeking intercession. In an act extraordinary for the era, the heirs of his master formally transferred his servitude to the Virgin herself, declaring him free from human masters but bound in service to the sacred image. "Slave of the Virgin, and nothing more," runs the phrase attributed to him. Manuel died in 1686 after more than fifty years of service, his life quietly anchoring a tradition that would eventually encompass an entire continent.
Successive chaplains built a series of chapels to house the growing pilgrimage. The first was a simple mud-brick oratory; by 1685 a more permanent chapel had been erected under the care of a Mercedarian friar, Padre Lazcano. In 1730 — a century after the miracle — a proper stone church was consecrated, its construction funded largely by the pious donations of Buenos Aires merchants. The colonial town that grew around it became, by royal decree in 1755, the Villa de Luján, with its own cabildo and civic administration.
The designation that transformed Luján from a regional shrine into a national one came in 1887, when Pope Leo XIII formally declared Our Lady of Luján patroness of Argentina. That same year, construction began on the present basilica to replace the colonial church now swamped by pilgrims. The architect was Ulrich Courtois, a Flemish Redemptorist, who designed a structure in the neo-Gothic style then fashionable for grand Catholic churches, drawing on the cathedrals of northern France and Flanders for his models. The foundation stone was laid on May 8, 1887 — the feast of Our Lady of Luján — on the western side of the colonial church, which remained in service throughout construction.
Building the basilica took forty-eight years. The main nave was roofed by 1910, allowing liturgical use, but the two great towers — their bells audible for miles across the pampa — were not completed until 1935. The interior is executed in French Gothic style: slender columns, ribbed vaulting, and an ensemble of stained glass windows produced in workshops in Chartres, France, and Buenos Aires. The overall impression is of extraordinary vertical aspiration: a building that seems to pull the eye and the spirit upward even before one reaches the high altar. Pope Pius XI elevated the church to a Minor Basilica in 1930, adding the formal title to a site that popular devotion had treated as a major sanctuary for three hundred years. In 1932 he further expanded the patronal designation, confirming Our Lady of Luján as patroness not only of Argentina but also of Uruguay and Paraguay.
The basilica's most sacred object is the tiny figure that started everything. The image of the Immaculate Conception measures 38 cm (about fifteen inches) and is made of a slightly reddish terracotta characteristic of the Bahian workshops of the early 17th century. The statue depicts the Virgin in the classic Immaculist posture: standing on a crescent moon, hands joined in prayer, her mantle — in the blue and white of the Argentine flag — falling to her feet. In 1887, to arrest the deterioration of the terracotta, the figure was fitted with a casing of solid silver that preserves its contours. Its crown contains 365 stones — diamonds, rubies, emeralds, and sapphires — one for each day of the year, along with 132 pearls and enamels bearing the emblems of the Argentine Republic and the archdiocese. The figure resides in the camarín, a chamber behind the high altar, visible through a glass opening that allows pilgrims to look directly upon the image from the nave.
The organized youth pilgrimage from Buenos Aires — the Peregrinación Juvenil — has its own distinct origin story. In 1975, a small group of young parishioners from the Buenos Aires neighbourhood of Villa Urquiza set out one October evening to walk to Luján. No one had organized a mass event; the impulse was spontaneous and personal. By morning, more than thirty thousand people were walking with them. The tradition took root immediately, growing each year until it became the largest regular movement of people in Argentine history. By 2024 the official count reached 2.3 million participants, with the theme "Madre, bajo tu mirada buscamos la unidad" (Mother, under your gaze we seek unity). The 68-kilometre walk from the barrio of Liniers — passing through the great western suburbs of Buenos Aires — is completed in a single night and morning, typically taking twelve to fifteen hours.
☩ Pilgrimage Sites in Luján
Basílica de Nuestra Señora de Luján
Basílica de Nuestra Señora de Luján
The great neo-Gothic basilica stands on the south bank of the Luján River, its twin towers marking the spiritual centre of Argentina with the same authority that Notre-Dame once commanded the heart of Paris. The exterior is built in grey stone quarried from the province of Córdoba, and the flying buttresses, rose windows, and elaborate portal sculptures reward slow examination. Inside, the nave extends 100 metres to the high altar, flanked by chapels housing the founding relics of the devotion: the chapel of San Luis de Montfort on the right ambulatory, the chapel of the original colonial church (Capilla del Blessed Sacrament) preserved within the basilica's southern arm, and the camarín behind the altar where the image of the Virgin resides.
The stained glass windows, produced in two distinct series — one from Chartres in the early 20th century, one from a Buenos Aires workshop — narrate the history of the devotion alongside scenes from the life of the Virgin and the national history of Argentina. Look for the window depicting Manuel, the African slave who became the image's first custodian; it is one of the few in any basilica to honour an enslaved person with a place in sacred glass.
The crypt below the main altar contains the tombs of several bishops of the diocese and a devotional chapel open to pilgrims throughout the day. Tower access (when available) offers panoramic views across the pampa and the Luján River valley.
The Camarín of Our Lady
The camarín — the chamber of the Virgin — is accessible by a passage behind the high altar and is the destination of every pilgrim who comes to Luján. The silver-clad figure of the Immaculate Conception sits in an illuminated niche at the chamber's centre, dressed in embroidered vestments that change according to the liturgical season. Pilgrims may pass through and venerate the image at close range; the atmosphere is intimate despite the basilica's monumental scale, and it is not unusual to find pilgrims weeping quietly or pressing photographs and prayer cards against the glass. The camarín opens to the nave through a large aperture behind the tabernacle, so the image is also visible — from a greater distance, in the full context of the basilica's Gothic space — during Mass.
🕯️ Annual Feast Days & Celebrations
Feast of Our Lady of Luján — May 8
The liturgical feast of Our Lady of Luján, observed annually on May 8, is the official patronal celebration of the basilica and the diocese. The day begins with a solemn sung Mass presided over by the Archbishop of Mercedes-Luján and often attended by bishops from across Argentina, Uruguay, and Paraguay. A candlelight procession around the basilica's exterior closes the celebration in the evening. May 8 is also the anniversary of the foundation stone of the current basilica (laid on this date in 1887), giving the feast a dual significance as both theological celebration and architectural memorial.
Peregrinación Juvenil — First Sunday of October
The Peregrinación Juvenil a Luján is, by any measure, one of the largest regular religious events in the world. On the first Saturday evening of October, pilgrims gather at the barrio of Liniers in western Buenos Aires — approximately 68 kilometres from the basilica — and begin walking through the night. The route follows Route 7 across the pampa through the suburbs of Morón, Merlo, and General Rodríguez, arriving at the basilica by mid-morning of Sunday. In 2024 more than 2.3 million people completed the walk, bearing candles, singing hymns, and carrying handwritten petitions. The pilgrimage has no single organizing body: it is sustained by hundreds of parish groups, youth movements, and informal groups of friends who simply choose to come. The official pilgrimage channel (LaPereLujan) broadcasts live throughout the night. First celebrated in October 1975 with a spontaneous gathering of 30,000 young parishioners, the Peregrinación has become the defining religious event of Argentine Catholic life.
Luján es Tradición — Last Sunday of September
From 1945 until 2022, the last Sunday of September saw the Peregrinación Gaucha: thousands of gauchos arriving on horseback from across Buenos Aires province to honour the Virgin in the most Argentine of idioms — on horseback, in traditional dress, to the sound of folk music and the smell of woodsmoke. In 2022, pressure from animal welfare organisations led the municipality to reformulate the event. The mounted pilgrimage in its traditional form was discontinued, replaced by a cultural festival called Luján es Tradición: a full day of gaucho folklore, traditional food, music, and exhibitions of equestrian skill without the long-distance ride. The gathering retains its atmosphere of deep Argentine popular Catholicism — a reminder that the Virgin of Luján is equally at home in the pulpería and the basilica — even if its form has changed. The pilgrimage's 82nd edition was celebrated on September 28, 2025.

🪶 Closing Reflection
"It is a long journey, but one that goes quickly — one that must be done. A journey to commemorate what the Virgin did there, she wanted to stay there. A journey of memory, of years and years of pilgrimage, of searching, of miracles, of daughters and sons who journey to see the Mother." — Pope Francis, Video Message for the Feast of Our Lady of Luján, May 6, 2021
