Construction of the church began in 1905 as a celebration of the 75th anniversary of Belgian Independence, but two world wars delayed its completion until 1970.

14. Metropolitan Cathedral of Saint Sebastian
Interior area: 8,000 m2 (86,111 ft2)
Dedicated to Saint Sebastian, the patron saint of Rio de Janeiro, this very large cathedral manages to appear futuristic and ancient at the same time. The church was constructed in a modernist style by Edgar de Oliveira da Fonseca based on ancient Mayan pyramidal architecture.
Upon its completion, this church replaced the Church of Our Lady of Mount Carmel of the Ancient See, now known as the “Old Cathedral,” as the seat of the Archdiocese in Rio de Janeiro. It is located in the center of the city and has a standing room capacity of 20,000 people.

In addition to its sheer size, a notable feature of the church is the artwork, which attracts many tourists. Some of the most famous pieces are paintings by Flemish artist Peter Paul Rubens.
The belfry in this cathedral is listed among the Belfries of Belgium and France as a UNESCO World Heritage Site. Although some were attached to churches, these belfries represented growing civic independence from feudal and religious influences in the region.

Interior area: 8,167 m2 (87,909 ft2)
Located in Mexico City, the Basilica of Our Lady of Guadalupe is one of the largest churches in the world and an important Catholic pilgrimage destination. It is the second-most-visited Catholic shrine in the world after St. Peter’s Basilica, drawing millions of visitors each year.

It was built in a Gothic style, with construction beginning in 1296 and structurally completed in 1436. It was originally designed by Arnolfo di Cambio, and the dome was engineered by Filippo Brunelleschi. The Cathedral’s exterior features a 19th-century Gothic Revival façade by Emilio De Fabris.
The dome of the Cathedral is especially significant as an architectural feat. Although it was constructed hundreds of years ago, it remains the largest masonry dome ever built.

According to local tradition, Mary appeared before Saint James as he was praying along the Ebro River around 40 AD. She gifted him a column of jasper and instructed him to construct a church in her honor at that location.
The first chapel is thought to have been built in the 1st century AD, and construction of the current version of the church began in 1681 by King Charles II of Spain. It was completed in 1686, though final touches were added in 1872.

The Basilica of Saint Paul Outside the Walls was constructed in the 4th century and is dedicated to Paul the Apostle who was thought to have been buried nearby. The church is one of the four major papal Basilicas in Rome, Italy.
Much of the original character of this basilica was retained for more than a thousand years before substantial damage was sustained due to a fire caused by a workman in 1823. Efforts were then made to rebuild the church in the image of its original construction, utilizing materials that survived the fire.
The interior of the basilica features intricate mosaics, frescoes, and marble columns. Also notable are the tomb of the Apostle and the cloister, which was built between 1220 and 1241.
8. Basilica of the Holy Trinity

The Basilica of the Holy Trinity is architecturally striking, with a modern, austere design in a circular shape. It was given the Outstanding Structure Award by the International Association for Bridge and Structural Engineering in 2009.

Number four on the list of largest churches is the Seville Cathedral, located in the Andalusia region of southern Spain. Together with the adjacent Alcázar palace complex and the Archivo General de Indias, the Cathedral has been listed as a UNESCO World Heritage Site since 1987.
The cathedral was constructed during the 15th century on a site where there had previously been a mosque. Construction was completed in 1506, although subsequent damage to the church’s crossing lantern required additional construction up until at least 1903.
Notably, the cathedral also houses the tomb of Christopher Columbus. The historical significance and grand architectural scale of the church make it a popular tourist attraction in Spain.
