Buenos Aires lies flat against the Río de la Plata, a river wide enough that the far bank belongs to another country, and the city Juan de Garay laid out on its western shore in 1580 carries a Marian name: Santa María del Buen Ayre, Our Lady of the Fair Wind, patroness of sailors. Her image in the Metropolitan Cathedral holds a caravel in her hands, and the port took her name before the streets did. A few paces from her altar stands that of Saint Martin of Tours, patron of the city by lot — the cabildo drew his name three times in succession before it accepted the draw as God's own preference.
The devotions sit far apart on a grid that takes an hour to cross. In the old city, within a few blocks of the Plaza de Mayo, are the cathedral and the Jesuit church of San Ignacio, the oldest building the city has kept. North in Recoleta, the whitewashed Basilica of Pilar keeps a silver altarpiece worked in Alto Perú and carried down the Camino Real. West, at the end of the Sarmiento railway line in Liniers, the shrine of San Cayetano draws the longest queue in Argentina every 7 August: workers asking for bread and work, and giving thanks for both.
Between those poles run the churches of Jorge Mario Bergoglio. In a side aisle of the Basilica of San José de Flores a confessional carries a plaque: a boy of seventeen went into it on the first day of spring in 1953 and came out intending to be a priest. In Villa Pueyrredón hangs a painted canvas of Mary drawing a long ribbon through her fingers, knot by knot — a German devotion the future pope brought home as postcards, which the city adopted as its own.
📜 History & Spiritual Significance
Garay set aside a quarter-block on the eastern side of his new plaza for the main church. The cathedral occupies that same ground. Five churches were raised on it and five came down: the first finished on the wrong plot, another built with rotten willow wood, a third whose tower and roof collapsed within a decade. In 1752 the vaults of the naves fell in overnight, and the bishop wrote to the king that the rest would have to be pulled down and begun from the foundations. The sixth church is the one a pilgrim walks into today.
Its front came last, and it is the front the city knows: twelve Corinthian columns under a flat pediment, on the model of the Palais Bourbon in Paris. The twelve are the apostles. Carved above them, Joseph meets his father and his brothers in Egypt — the forgiveness of the men who sold him, set over the door of a country then tearing at itself in civil war. Inside, off the right aisle, grenadiers keep watch over the black sarcophagus of José de San Martín, the general who freed Argentina, Chile and Peru; his remains came home from France in 1880, and three carved women stand guard for the three countries.
Until 2024 this was the primatial church of Argentina. Pope Francis transferred that rank to the cathedral of Santiago del Estero, where the country's first diocese was raised, and Buenos Aires kept what it had been from the start: the mother church of its own archdiocese, and the church where Jorge Bergoglio celebrated Mass as archbishop for fifteen years before the conclave of 2013. When he died on 21 April 2025 the cathedral filled with mourners, and the archbishop, Jorge García Cuerva, called him the pope of the poor.
Recoleta was farmland when the Franciscan Recollects were given a plot there. The Aragonese merchant who paid for their church attached a condition — that it be dedicated to the Virgin of the Pillar of Zaragoza — and the church opened on 12 October 1732, her feast day. The friars were expelled in the ecclesiastical reform of the 1820s and the convent orchard became the Recoleta Cemetery, so that the small colonial basilica now keeps its silver behind the most visited graveyard in Argentina.
The Jesuits built in brick before anyone else. The south tower and front wall of San Ignacio were raised in 1686 out of the first kilns in Buenos Aires and are the oldest built work in the city; the church behind them, finished in 1722 on a plan drawn from the Gesù in Rome, is the oldest standing. When the order was expelled in 1767 the block around it passed to the state — a school of medicine, the national library, a university inaugurated inside the church itself — and the church stood in for the cathedral while the sixth cathedral was being finished. Colonial defence tunnels run underneath, and one of them is open.
Liniers is a working suburb, and the devotion that made it a place of pilgrimage began there with a chapel and school opened by the Daughters of the Divine Saviour in 1875. It became what it is in the 1930s, when the crisis emptied the workshops and a parish priest, Domingo Falgioni, preached Cajetan of Thiene — who died in Naples on 7 August 1547 — as the patron of bread and work. Argentine workers took him for their own. The 7th of August is now the largest single day of pilgrimage the city keeps, and the shrine at Cuzco 150 is where the walk to Luján sets out each October.
The Bergoglio family lived a few blocks from the Basilica of San José de Flores and heard Sunday Mass there. On 21 September 1953, the day Argentines keep as the first of spring, Jorge went into the church on his way to meet friends, found a priest he did not know, and asked to make his confession; he said afterwards that he left it knowing he would be a priest. As cardinal he kept saying Mass at Flores, above all on 19 March, the feast of Saint Joseph, and he chose that feast for the beginning of his pontificate.
The last of his Buenos Aires devotions he found abroad. Visiting Germany in the 1980s he saw in the church of St Peter am Perlach in Augsburg a canvas painted about 1700 by Johann Schmittdner, showing Mary untying a long knotted ribbon, and he had postcards of it printed and gave them away at Christmas. One reached the painter Ana María Betta de Berti, who copied the image at full size, and on 8 December 1996 it was enthroned in the parish of San José del Talar at his asking. He gave the parish priest a line of Saint Irenaeus to bless it by: what Eve tied by her disobedience, the Virgin Mary untied by her obedience to God.
☩ Pilgrimage Sites in Buenos Aires
Metropolitan Cathedral of the Most Holy Trinity
Catedral Metropolitana de la Santísima Trinidad
The portico gives no hint of what is behind it: five naves, the central one under a barrel vault, and a floor of Venetian mosaic whose pattern carries the passionflower, mburucuyá in Guaraní. The gilt Rococo altarpiece holds the Trinity in its canopy. In an arm of the transept is the Christ of Buenos Aires, a seventeenth-century carving and the oldest sculpture in the building, which the faithful hold turned back a flood. The altar of Saint Martin of Tours stands along the right nave, and with it the Virgin of Buen Ayre with her caravel, the title the city was named for. A German organ of more than three thousand pipes was installed in the nineteenth century. Three rooms to the left of the central nave hold the personal and liturgical objects of Jorge Bergoglio's fifteen years as archbishop, opened as a museum in the months after his election; a life-size statue of him was put up and then taken away at his own request.
Basilica of Our Lady of Pilar
Basílica de Nuestra Señora del Pilar
A plain whitewashed colonial church set at an angle to the street grid, with a two-arched bell-gable carrying a spherical clock made in London — held to be the first clock the city had. The single nave opens into a broad transept under a sail vault. The Baroque main altarpiece carries the Virgin of the Pillar between two Franciscan saints, its silver worked in Alto Perú and brought down the Camino Real by mule; the image venerated there is the one the friars carried in. A carving of Saint Peter of Alcántara, co-patron of the church, stands nearby, and the altar of relics is held by tradition to be a gift of Carlos III of Spain. Three storeys of the original cloister survive as a small museum of paintings, manuscripts and liturgical objects, its windows looking down over the Recoleta Cemetery. The parish keeps perpetual adoration.
Church of San Ignacio de Loyola
Iglesia de San Ignacio de Loyola
The oldest church standing in Buenos Aires, at the corner of the Manzana de las Luces. One nave runs under a barrel vault with five chapels opening off each side through arcades; above them runs a gallery built so that priests could cross the church without disturbing a Mass, which also keeps the direct light off the floor below. The main altar was carved and gilded in the seventeenth century. In a lateral altar rest the remains of Juan José Castelli, of the first revolutionary junta. The image a pilgrim should look for is Our Lady of the Snows, brought from Spain in the sixteenth century: the oldest image in the city, and its second patroness after Saint Martin of Tours. Part of the colonial tunnel system runs beneath the building and one stretch is open to visitors.
Basilica of San José de Flores
Basílica de San José de Flores
The church of Pope Francis's childhood, facing the Plaza Pueyrredón on Avenida Rivadavia, framed by three covered passages. What pilgrims come for is the first confessional on the left as one enters by the side nave, marked with a plaque: the place where a seventeen-year-old Jorge Bergoglio made the confession that decided his vocation. The image of Saint Joseph at the high altar was crowned by Pius XII, and the basilica keeps relics of Saint Columba, virgin and martyr, brought from Rome. A Caritas kitchen feeds more than two hundred and fifty people from the parish buildings, which is the other thing worth knowing about this church.
Shrine of San Cayetano
Santuario de San Cayetano de Liniers
The principal shrine of Saint Cajetan in Argentina, patron of bread and work, beside the Liniers station of the Sarmiento line. On 7 August the queue of workers reaches down the street for blocks; the Archbishop of Buenos Aires celebrates a Mass for them, tools of the trade are blessed, and people come as much to give thanks for work found as to ask for work wanted. From the doors of this shrine the youth pilgrimage to Luján sets out on the first Saturday of October and walks through the night to the national basilica — the largest regular movement of people in Argentina, first walked in 1975 by some 30,000 young people from Liniers. Dates and route are published by the organisers; the shrine at the far end has its own guide.
Sanctuary of Our Lady Undoer of Knots
Santuario de Nuestra Señora que Desata los Nudos
A parish church in Villa Pueyrredón, on a residential street far from any tourist route, holding the painted copy of the Augsburg image that Jorge Bergoglio brought to Argentina. The canvas was enthroned in 1996 and crowned in 2021 by Cardinal Mario Aurelio Poli, with a message sent from Rome by the pope who had given the devotion to the city. Pilgrims bring the knots of their own lives — the illness, the estrangement, the debt — and hundreds gather on the eighth of every month, the day of the Immaculate Conception on which the image first hung here.
🕯️ Annual Feast Days & Celebrations
Feast of Saint Joseph — March 19
The titular feast of the Basilica of San José de Flores, kept with particular solemnity in the church where Pope Francis heard Mass as a boy and where he returned to celebrate it as cardinal. He chose the same feast for the inauguration of his pontificate.
Feast of Saint Ignatius of Loyola — July 31
The titular feast of the Jesuit church on Bolívar, kept on the universal feast day of the founder of the Society of Jesus.
Feast of San Cayetano — August 7
The largest pilgrimage day in Buenos Aires. Workers walk to the shrine in Liniers through the night and the morning, in a queue that runs for blocks, to ask for bread and work and to give thanks; the Archbishop of Buenos Aires celebrates a Mass for workers and blesses the tools of their trades. Sheaves of wheat are carried and left at the shrine.
Feast of Our Lady Undoer of Knots — September 28
The annual feast of the devotion at San José del Talar, where the copy of the Augsburg image is venerated. The monthly gathering on the eighth of each month is the same devotion at smaller scale.
Our Lady of the Pillar — October 12
The feast of the Zaragoza devotion the Recoleta basilica was dedicated to, and the anniversary of the day the church opened.
Feast of Saint Martin of Tours — November 11
The feast of the patron of the city, chosen by lot at the cabildo in the year of the foundation. The archdiocese keeps a triduum before it and a solemn Mass at the cathedral, where the saint's altar stands in the right nave.

🚗 Getting There
By Air: Ministro Pistarini International Airport, known to everyone as Ezeiza (EZE), lies about 30 km from the centre; the drive takes 45 to 60 minutes, longer in the rush hour. Jorge Newbery (AEP), on the river north of the centre, handles domestic and regional flights. No train serves Ezeiza.
By Bus: Manuel Tienda León runs a shuttle from Ezeiza to a terminal in Puerto Madero, with connections to Retiro and to Jorge Newbery. The public bus, Line 8, runs from Ezeiza to the Plaza de Mayo for a fraction of the price and takes more than two hours; it requires a SUBE card, bought and loaded before boarding.
By Car: Official taxi and remis desks are inside the arrivals hall, with set fares by neighbourhood — book at the desk rather than accepting a ride offered on the concourse. Uber and Cabify pick up at marked points outside the terminal.
Local Transport: The head stations of subway lines A, D and E meet at the cathedral, where Avenida Rivadavia crosses San Martín, which makes the old-city churches the easiest group to visit. Agüero and Facultad de Medicina are the nearest stations to the Basilica of Pilar. San Cayetano is beside Liniers station on the Sarmiento suburban railway. A SUBE card covers subway, bus and train.
