What Makes A Cathedral A Cathedral?
A cathedral is a center of worship and mission that houses a bishop's official seat, or “cathedra,” making it the administrative and spiritual center of a diocese. Bishops typically reside on the cathedral premises, which is important to local heritage, culture and community life. Several religions are practiced in cathedrals, including Roman Catholic, Eastern Orthodox, Anglican and Lutheran.
Many beautiful churches in Europe rival the beauty of European cathedrals, but differ in function. A church is usually managed by clergymen or a priest, whereas a cathedral is under the pastoral care of a bishop. Cathedrals are also distinct from a basilica, which is designated by the Pope for its historical, spiritual or architectural importance, regardless of whether it houses a bishop. Simply put:
- ● A Cathedral is a bishop’s church and the center of a diocese.
- ● A Basilica is a church with special status granted by the Pope.
- ● Church is a general term denoting a place of worship.
The Greatest European Cathedrals: Famous, Beautiful and Unforgettable
1. La Sagrada Família — Barcelona, Spain
La Sagrada Família is one of the most famous cathedrals in Europe. However, its fame stems from the fact that it's the world's largest unfinished Roman Catholic Church. Renowned Catalan architect Antoni Gaudí designed the cathedral for vibrant Barcelona. Construction began in 1882 but ceased when Gaudí — who is buried onsite — passed away in 1926, with less than a quarter of the cathedral complete. Construction slowly resumed in the 1950s, and it finally passed the halfway point in 2010. The expected completion date is 2026 — the 100th anniversary of Gaudí's death.
La Sagrada Família is one of the coolest cathedrals. Here are some fascinating facts to back that up:
- ● Its architecture represents a fusion of Gothic Revival, Art Nouveau and Catalan Modernism.
- ● It boasts unique features, including the three iconic Glory, Nativity and Passion facades, respectively facing south, east and west.
- ● The cathedral will have 18 spires that symbolize the Twelve Apostles, the Virgin Mary, the four Evangelists and Jesus Christ, once complete.
- ● Each spire will increase in height to visually represent the hierarchy, with the Jesus Christ spire slated to reach 560 feet.
Millions of people visit La Sagrada Família annually, making it Barcelona's most-visited tourist attraction.
While Barcelona is obviously a main tourist destination, other areas of Spain will not disappoint. Try exploring other cities, like Seville, with its own stunning churches and architecture
2. Notre-Dame De Paris — Paris, France
Another European cathedral currently under construction is Notre Dame de Paris, often simply referred to as Notre Dame. This medieval Catholic cathedral, located on Île de la Cité in Paris, is one of the world's finest examples of French Gothic architecture. Dedicated to the Virgin Mary, its iconic features include:
- ● Stained-glass rose windows.
- ● Three pipe organs.
- ● Vaulted ceilings.
- ● The roof, often called "the forest,” as every beam was built from an individual tree.
Notre Dame is known as a Gothic trendsetter featuring:
- ● Exterior flying buttresses: Quintessential to Gothic architecture, the buttresses were built to support the thin walls and large stained-glass windows.
- ● Chimeras and gargoyles: These gothic creatures are arranged outside the building's exterior.
- ● Christian relics: Inside the cathedral, you can find the Crown of Thorns and both a sliver and a nail from the True Cross.
Victor Hugo's 1831 novel, Notre Dame de Paris (often translated as The Hunchback of Notre Dame), garnered renewed interest in the cathedral, and the momentum led to a major renovation. Today, it's one of the most widely recognized symbols of both Paris and France. In fact, approximately 12 million people visit Notre Dame annually, making it Paris' most visited attraction.
After it survived both the French Revolution and World War II, the world was left heartbroken when Notre Dame's roof caught fire in 2019 and burned for nearly 15 hours. After several years of work, Notre Dame was restored and officially reopened on December 7, 2024.
Iconic Italian Cathedrals

4. Milan Cathedral (Duomo di Milano) — Milan, Italy
Officially known as the Metropolitan Cathedral-Basilica of the Nativity of Saint Mary, the Milan Cathedral is dedicated to the Nativity of St. Mary. Like many of its counterparts, it took six centuries and thousands of workers to complete its construction. It began in 1386, but the cathedral didn't receive its finishing touches until 1965.

Try not to get sidetracked by the stunning interior, where you'll find the cathedral's most famous sculpture, the sparkling gold Little Madonna, on top of the tallest spire.
Milan is truly a gem and one of the best European cities to visit.

5. Cologne Cathedral — Cologne, Germany
Cologne Cathedral is a renowned monument of both German Catholicism and Gothic architecture. Construction began in 1248, ceased in the 16th century and was finally completed to its original Medieval plan in 1880. It's seen a lot of historic moments over the centuries, being used as a stable during the French Revolution and getting damaged by Allied air raids in World War II.

6. St. Paul’s Cathedral — London, England
St. Paul’s Cathedral is the Diocese of London's mother church. Standing tall on Ludgate Hill, the Grade I listed building is the City of London's highest point. Its dedication to Paul the Apostle stretches back to the original church on the site in A.D. 604. The current structure, designed by Sir Christopher Wren in the late 17th century, is in the English Baroque architectural style with neoclassic and Gothic touches.
Defining features include:

St. Paul's Cathedral is also well known for its art exhibitions, with artwork stretching over the centuries. A burial, memorial or celebration in St. Paul's Cathedral remains one of the highest national honors. It was the site of Winston Churchill's funeral and Prince Charles and Princess Diana's wedding. While there is a tourist fee to enter, it's a working church, so there's no cost for worshipers to attend services.
London is a must-visit on any vacation that includes history and architecture as well as fun and adventure.
