Five of the Most Extraordinary Churches to Visit in the World

Some of the world's greatest churches are famous enough to need no introduction. St. Peter's Basilica, Notre-Dame, and the great basilicas of Rome attract millions of visitors every year.

But for travelers and pilgrims looking beyond the most obvious destinations, there are extraordinary churches whose stories are just as compelling. Some preserve the memory of saints, others stand at the center of centuries-old pilgrimages, and some are masterpieces of art and architecture unlike anything else in the Christian world.

Here are five remarkable churches worth traveling to see.

Few churches capture the spirit of a saint as powerfully as the Basilica of St. Francis in Assisi.

Built after the death of St. Francis in the thirteenth century, the basilica contains his tomb and became one of the great centers of Franciscan spirituality. Its unusual design includes an Upper Church and Lower Church, creating a dramatic progression from soaring light to a more intimate and contemplative space below.

The basilica is also one of the great landmarks of medieval art. Its frescoes include works associated with some of the most influential artists of the period, and UNESCO describes Assisi and its Franciscan sites as a major reference point in the development of Italian and European art and architecture.

For a Catholic pilgrim, however, the greatest reason to visit is not the art alone. To pray near the tomb of St. Francis is to encounter the legacy of a man whose message of simplicity, peace, and radical devotion to Christ continues to resonate around the world.

Why it stands out: A rare combination of profound spirituality, medieval art, and one of Christianity's most beloved saints.

Tucked away on the Île de la Cité, Sainte-Chapelle can be easy to overlook beside the more famous monuments of Paris. Yet stepping inside feels like entering a building made almost entirely of light.

Completed in the thirteenth century for King Louis IX, the chapel was built to house precious relics associated with the Passion of Christ. Its upper chapel is celebrated for an extraordinary collection of stained-glass windows that tell biblical stories in brilliant color.

The official monument site describes Sainte-Chapelle as a jewel of Rayonnant Gothic architecture and highlights its remarkable stained-glass ensemble.

Unlike the massive cathedrals of Europe, Sainte-Chapelle feels almost intimate. Its slender stone structure seems to disappear behind walls of glass, creating an atmosphere that is both artistic and deeply devotional.

Why it stands out: Perhaps the most breathtaking stained-glass experience in the world.

For a truly global perspective on Catholicism, few churches are more impressive than the National Shrine of Our Lady of Aparecida.

The shrine is dedicated to Our Lady of Aparecida, the patroness of Brazil. Its devotion began with a small image of the Virgin Mary found by fishermen in the Paraíba River in 1717. Over the centuries, devotion grew into one of the largest Marian pilgrimages in the world.

Today, the immense basilica welcomes pilgrims from throughout Brazil and beyond. Its scale is striking, but the heart of the pilgrimage remains the small and much-loved image of Our Lady of Aparecida.

The contrast between the modest image and the enormous shrine built around it offers a powerful reminder that great movements of faith often begin in unexpected ways.

Why it stands out: One of the world's great Marian shrines and an unforgettable expression of Catholicism beyond Europe.

Some churches are remarkable because of what stands inside them. Santiago de Compostela is remarkable because of the journey that leads to it.

For more than a thousand years, pilgrims have traveled the routes of the Camino de Santiago, or Way of St. James, toward the cathedral traditionally associated with the burial place of St. James the Apostle.

Arriving at the cathedral after days—or even weeks—of walking gives the church a significance that is difficult to reproduce through an ordinary sightseeing visit. The journey itself becomes part of the prayer.

The cathedral is a remarkable blend of architectural styles, shaped over centuries by the needs of pilgrims and the changing artistic life of Spain.

For Catholics, its greatest significance lies in its connection with one of Christ's Apostles and with one of the world's oldest continuing pilgrimage traditions.

Why it stands out: The destination is inseparable from one of Christianity's greatest pilgrimage experiences.

Just outside Palermo stands one of the most spectacular churches in the Mediterranean: Monreale Cathedral.

Built in the twelfth century, the cathedral is famous for its extraordinary Byzantine mosaics. Inside, shimmering gold backgrounds and detailed biblical scenes cover vast sections of the church, creating an effect that is both overwhelming and deeply contemplative.

Monreale is also a remarkable example of Sicily's complex cultural history. Its architecture reflects the meeting of Norman, Byzantine, and Arab artistic traditions.

UNESCO includes the cathedral among the Arab-Norman monuments of Palermo and the cathedral churches of Cefalù and Monreale, recognizing the extraordinary cultural and artistic heritage of this part of Sicily.

For visitors accustomed to the churches of Rome or Florence, Monreale offers something entirely different: a Christian vision expressed through the luminous visual language of the Eastern Mediterranean.

Choosing only five churches means leaving out many extraordinary places. Travelers looking for even more unusual destinations might consider:

The Basilica of Our Lady of Guadalupe in Mexico City — one of the world's most important Marian shrines.

The Church of the Holy Sepulchre in Jerusalem — among Christianity's most sacred sites

Basilica of St. Anthony in Padua, Italy — a major pilgrimage destination associated with one of the Church's most beloved saints.

Basilica of the National Shrine of the Immaculate Conception in Washington, D.C. — an extraordinary collection of chapels and sacred art representing Catholic communities from around the world.

Sagrada Família in Barcelona — a daring and still-unfolding vision of Christian architecture.

The world's great churches are not simply museums or architectural attractions. They were built for worship, and the best way to experience them is to leave time for something more than photographs.

Attend Mass if possible. Sit quietly. Light a candle. Pray before a saint's tomb. Study the stained glass or mosaics not simply as art, but as a visual expression of the Christian story.

The most memorable church may not always be the largest or the most famous. Sometimes it is the place where history, beauty, and prayer come together—and where a traveler unexpectedly finds a moment of silence in the middle of the world.
