Inside the Architecture of Basilica Sagrada Familia in Barcelona

It takes decades to build an awe-inspiring structure. The medieval age is full of cathedrals and churches reflecting beauty and artistry through the intricate artwork of skilled craftsmen. It is fascinating to notice the life-size sculptures, handcrafted nature motifs, baroque architecture, and exquisite paintings. The churches in the medieval era are adorned with paintings of Michelangelo and Bernini.

Modern architecture is evolving with creativity, innovative designing, and construction techniques. One such cathedral that remains unfinished to this date is the Sagrada Familia in Barcelona, Spain, even though the construction began 136 years ago. The construction of this Basílica is the most sought-after piece of architecture in the world today.

The construction first started on 19th March 1882. This Basilica is designed by famous architect Antoni Gaudi. It is also a UNESCO World Heritage Site. The tentative year of completion is estimated to be 2026. Some of the world’s most talented architects and designers are involved in the construction of this legendary church. The construction techniques used for this project have evolved over the decades. The materials and construction techniques used in the Basilica de la Sagrada Familia are world-class. The best cement for roof concrete is Ordinary Portland Grade 53 variety.

This Basilica stands at a towering height of 172meters which makes it the tallest church in the world. It covers an area of 9000sq. meters in central Barcelona. There are 18 towers in the Basilica, each related to a Christian figure. The middle tower is dedicated to Jesus Christ and the surrounding towers to Virgin Mary, Mathew, Mark, John, Luke, and others. The entire church projects an iconography relating to Christian faith. The Glory façade is designed to feature verses from The Holy Bible.

Let’s understand the materials and construction techniques being used for this church. The bell towers in the church are made of Montjuic sandstone. And other towers are made of granite. The tallest tower reaching a height of 172 meters devoted to Jesus Christ stands at the center of the Basilica, topped with a 30-meter tall cross. This tower features a 60-meter high parabolic staircase to allow visitors to access the spire. White concrete is used for the construction of pillars and the walls of the church.

The increasing height of a building contributes to compression loads in the base of the structure. Innovative construction techniques are incorporated to ensure that the structure can withstand huge compression loads while sustaining its shapes and sculptures.

It features an eclectic mix of traditional and modern architecture. The theme of intricate artwork engraved inside the church is inspired by baroque and medieval architectural designs. This will serve as an inspiration to all engineers and architects for modern-day construction work.
