Faith meets divine architecture at these five largest Cathedrals in the world

  1. St. Peter’s Basilica

Address: Vatican City

Size/Area covered: 15,160m²

St. Peter's Basilica is not simply the biggest church in the world, but it is a monument of the Catholic Church and one of the greatest pieces of architecture produced during the Renaissance era. Designed by legends such as Michelangelo and Bernini, it took more than a century to finish.

Once you enter the church, it is impossible not to be taken to another world by the enormous dome high above your head, which is 136 meters above the floor. 

Observe the golden light reflecting off the mosaic and marble surfaces while Michelangelo's Pietà silently rests near the entrance. Above St. Peter's tomb is the enormous altar canopy. Although the basilica is vast, one can still feel that the church is very spiritual. 

Travel Tip: Ascend the dome for spectacular views over Vatican City and the rest of Rome. 

  2. Basilica of the National Shrine of Our Lady of Aparecida

Address: Aparecida, Brazil

Size/Area covered: 12,000 m²

Located in the tiny Brazilian town of Aparecida lies South America’s largest cathedral, and the second largest by area in the world. The basilica is a 20th-century structure dedicated to Our Lady of Aparecida, Brazil’s patron saint. 

The brick building is boldly modern yet warm and welcoming. Inside, the building features mosaics in vibrant colors, blue-tiled chapels, and devotional spaces in which thousands of people come to pray and contemplate.

Travel tip: If you are planning to visit in October, you should try to go around the Feast Day held on October 12 to have a profound cultural and spiritual experience. Advance lodging arrangements are advised as there are limited accommodations.

  3. Milan Cathedral (Duomo di Milano)

Address: Milan, Italy

Size/ Area covered: 11,700 m²

Few buildings can stun you like the Duomo di Milano. Multiple marble spires and thousands of statues make it one of the most elaborate buildings in Europe. The cathedral's construction began in 1386, but it wasn’t until the 20th century that it was completed, an effort that spanned centuries.

The outside is overwhelming, but the inside is just as powerful. The cathedral features huge glass windows that are stained cast magnificent colors across the marble floors. The central nave is so grand that it feels like walking into a canyon filled with light and stone.

However, the absolute best spot is on the rooftop. Walking amongst the cathedral's flying buttresses and delicate pinnacles, you will feel like you are on a movie set for a fantasy film and will see Milan spread below.

Travel Tip: Book a rooftop ticket ahead of time. Take the elevator up to the rooftop and walk down. Less crowded, and you get two views of one of the most incredible structures you have ever seen.

  4. Seville Cathedral

Address: Seville, Spain

Size/Area covered: 11,500 m²

Seville's Cathedral is a stunning blend of Islamic and Gothic architecture. Constructed in the 15th century on the site of the previous mosque, it was the world's largest Gothic cathedral, and also the burial site of Christopher Columbus.

The most distinguishable feature is the bell tower (originally the minaret) known as the Giralda. Now, it offers stunning panoramic views to visitors from around southern Spain. The interior of the Cathedral is no less awe-inspiring, from the soaring ceilings, to the great golden altar, to the hundreds of chapels, every nook has something to take in.

Considered one of the most elaborate altars in the world, the Retablo Mayor, which is the Main Altar, is covered in gold leaf and displays hundreds of figures from the Holy Book. There are not only different faith traditions represented, but also many eras. In a way, you can take a story of Spain and see many chapters.

Travel Tip: Climb the Giralda tower, the ramp design here makes it ascent with 34 floors doable for most, including families.

  5. Cathedral of Saint John the Divine

Address: New York City, United States

Size/Area covered: 11,200 m²

Fashioned in the Gothic Revival style, located here in Morningside Heights, this is the world's largest Anglican cathedral, and the second largest church in terms of interior volume. In the vernacular, it is regularly called around town "St. John the Unfinished" because it has remained incomplete since 1892. 

Inside, it has a nave longer than a football field, rows of huge stone columns rising are present for the awesome spiritual experience, and the rose window includes over 10,000 pieces of glass. Although you may encounter many visitors, it acts like a sanctuary of peace, even a mystique. 

The cathedral is more than just an active church; it serves as a cultural hub. It regularly features art exhibits, music performances, and social justice events. It is not only a place of worship, but the cathedral is truly part of a living New York. 

Travel Tip: Try to time your visit to the cathedral to one of their signature events, such as the Blessing.
