More than 140 years after construction began, Barcelona's famous Sagrada Familia has reached a milestone many thought they might never see. On June 10, 2026, Pope Leo XIV inaugurated and blessed the Tower of Jesus Christ, the basilica's tallest and most important tower, officially making the Sagrada Familia the tallest church in the world.

The moment carried extra significance because it came exactly 100 years after the death of Antoni Gaudí, the visionary architect who transformed the project into one of the most ambitious buildings ever attempted. With Spain's royal family, senior officials and thousands of worshippers in attendance, the ceremony marked a major chapter in a story that began in the 19th century and is still being written today.

Pope Leo XIV Marks A Historic Milestone In Barcelona

Thousands gathered in Barcelona as Pope Leo XIV presided over a special Mass at the Sagrada Familia to bless the newly completed Tower of Jesus Christ, now the tallest structure in the basilica and the crowning achievement of Antoni Gaudí's vision.

The ceremony drew some of Spain's most prominent figures, including King Felipe VI, Queen Letizia and Prime Minister Pedro Sánchez, alongside church leaders, dignitaries, pilgrims and visitors from around the world.

Adding a local touch to the occasion, the Pope addressed the congregation in Spanish and Catalan, while parts of the liturgy were conducted in Latin. Following the blessing of the illuminated cross atop the tower, celebrations spilled beyond the basilica with a spectacular light show, drone display and fireworks that lit up Barcelona's skyline.

The event was especially meaningful because it took place exactly 100 years after Gaudí's death in 1926, linking the architect's legacy directly to one of the most significant milestones in the basilica's history. The completion of the Tower of Jesus Christ marks a major step toward realizing the masterpiece that Gaudí devoted the final years of his life to creating.

The Sagrada Familia Is Now The Tallest Church In The World

With the completion of the Tower of Jesus Christ, the Sagrada Familia has officially reached its planned height of 172.5 metres (566 feet), making it the tallest church in the world.

The record was achieved through the completion of the central tower dedicated to Jesus Christ, the highest point of the entire basilica.

Interestingly, Gaudí deliberately chose not to build higher. He designed the structure to remain slightly shorter than Barcelona's Montjuïc hill because he believed that human creations should not exceed the natural creations of God.

What Exactly Is The Sagrada Familia?

The Sagrada Familia, officially known as the Basílica i Temple Expiatori de la Sagrada Familia, is a Roman Catholic basilica located in Barcelona's Eixample district.

Designed by Antoni Gaudí, it has become one of the most recognised landmarks in the world and the defining symbol of Barcelona for many visitors.

The church is also part of the UNESCO World Heritage listing that includes several of Gaudí's architectural works.

A Project That Began In The 19th Century

Construction began on March 19, 1882, under architect Francisco de Paula del Villar, who envisioned a conventional neo-Gothic church.

A year later, Gaudí took over the project and transformed it into something entirely different.

Rather than following traditional church architecture, he introduced bold forms inspired by nature, geometry and Christian symbolism. More than 140 years later, builders are still working to bring his vision to life.

Gaudí devoted over four decades to the basilica and spent the final years of his life almost entirely focused on the project. Today, he is buried in the church's crypt.

Why The Building Looks Unlike Any Other Church

Step inside the Sagrada Familia and one thing becomes immediately clear: this is not a typical cathedral.

Gaudí drew inspiration from the natural world rather than rigid architectural traditions. The interior columns branch upward like trees, creating the feeling of standing inside a vast forest made of stone.

Throughout the basilica, visitors can find spirals, hyperboloids and geometric forms that mirror patterns seen in nature. Sunlight streaming through the stained-glass windows adds another layer to the experience, transforming the interior throughout the day.

The Meaning Behind The Basilica's 18 Towers

Every tower at the Sagrada Familia has a symbolic purpose.

The complete design includes 18 towers:

• 12 towers representing the Apostles
• 4 towers representing the Evangelists Matthew, Mark, Luke and John
• 1 tower dedicated to the Virgin Mary
• 1 central tower dedicated to Jesus Christ

The newly inaugurated Tower of Jesus Christ is the tallest of all 18 towers and serves as the spiritual and architectural centrepiece of the basilica.

The Three Facades Tell The Story Of Christ

One of the most fascinating aspects of the Sagrada Familia is that its exterior functions almost like a stone Bible.

• The Nativity Façade focuses on the birth of Jesus, family life and hope. It is particularly significant because it was largely completed under Gaudí's direct supervision.
• The Passion Façade presents the suffering, crucifixion and death of Christ. Its sharp lines and dramatic sculptures create a striking contrast to the Nativity Façade.
• The Glory Façade, which is still under construction, explores themes of resurrection, heaven and humanity's path towards God. Once completed, it will become the basilica's principal entrance.

Why Has Construction Taken So Long?

When people hear that the Sagrada Familia has been under construction for more than 144 years, the first question is usually the same: why?

The answer lies in a combination of challenges.

• The project has largely depended on private donations and visitor revenue rather than direct government funding. Construction also suffered major setbacks following Gaudí's death in 1926.
• During the Spanish Civil War, many of the architect's original drawings and models were destroyed, forcing later generations to reconstruct parts of his vision using fragments, photographs and surviving sketches.
• The sheer complexity of the design, modern engineering requirements and even pandemic-related disruptions in 2020 have further extended the timeline.

A Church That Was Consecrated Before Completion

Despite being unfinished, the Sagrada Familia has long functioned as an active place of worship.

In 2010, Pope Benedict XVI consecrated the church and elevated it to the status of a minor basilica.

That means religious services have been held there for years, even as construction crews continued their work around the site.

Millions Of Visitors Help Keep The Project Moving

The Sagrada Familia is one of Europe's most visited attractions, drawing millions of visitors every year.

Ticket sales and tourism revenue play a major role in funding ongoing construction, helping builders continue work without relying heavily on public funding.

In many ways, visitors have become part of the project itself, contributing to a structure that has spanned multiple generations.

Is The Sagrada Familia Finally Finished?

Not yet!

While the completion of the Tower of Jesus Christ marks one of the most important milestones in the basilica's history, work continues on the Glory Façade, the monumental staircase and several surrounding elements.

The church has reached its final height, but the broader project still has years of work ahead before Gaudí's vision is fully realised. Current estimates suggest construction could continue into the 2030s.

From Gaudí's Dream To A Global Landmark

The Sagrada Familia has survived wars, financial challenges, changing technologies and the passage of time itself. What began as a church project in 1882 has evolved into one of the most ambitious architectural undertakings ever attempted.

The blessing of the Tower of Jesus Christ highlights that some visions outlive their creators. More than a century after Antoni Gaudí's death, the basilica he dedicated his life to has become the world's tallest church and remains one of humanity's most remarkable examples of faith, art and engineering working together.
