Picture yourself walking through the heavy wooden doors of a centuries-old cathedral, mosque, or any monumental religious structure.

Your eyes naturally drift upward, mesmerised as coloured light dances across the stone floors, and an overwhelming sense of peace washes over you.

What you're experiencing is the result of a carefully crafted symbolic language that speaks directly to the human spirit. Religious architecture is one of the earliest examples of storytelling in structures.

From the megalithic structures of Göbekli Tepe (Turkey, circa 9600 BCE) and Stonehenge (UK, circa 3000 BCE) to the Gothic cathedrals of the Middle Ages, every design feature carries meaning that extends beyond aesthetics.

In today's issue, we’ll consider how sacred architecture uses symbolic architectural elements to tell stories and create religious experiences.

Let's dive in!

Stained glass windows are perhaps the most recognisable feature of Christian religious architecture. Their use in sacred spaces dates back to the 4th century, with simple decorative windows in chapels and monasteries.

By the Middle Ages, stained glass and rose windows had become a defining feature of Gothic cathedrals, serving as visual educational tools for a largely illiterate society.

Architectural features like flying buttresses and pointed arches allowed for larger windows on which biblical artworks were created.

Beyond telling stories and moral lessons through vivid imagery, stained glass was used to create the experience of divine presence. The way sunlight filters through these coloured windows was interpreted as a metaphor for godly light.

It transformed the interior into a sacred and contemplative space. Stained glass continues to be used in sacred spaces for the same reasons: to evoke emotion, inspire reflection, and connect us to the divine.

Domes are a universal symbol of the heavens, found across cultures and religions. In Christian Byzantine architecture, the dome is often decorated with images of Christ or celestial scenes.

Islamic architecture employs domes to symbolise the unity and infinity of Allah, while Hindu and Buddhist temples use them to represent the cosmic egg from which creation emerges.

The dome's circular form has no beginning or end, making it a perfect metaphor for eternity and divine perfection. Domes evoke a sense of monumentality of the divine, infinite but also encompassing.

Similarly, ribbed and barrel ceiling vaults in Gothic cathedrals create a sense of awe and smallness that naturally induces reverence.

Unlike Christian religious spaces, which often use figurative imagery on windows and walls, Islamic religious art typically employs geometric forms.

As Islamic scholars expanded upon Greek, Persian, and Indian mathematical traditions, geometry became a central aspect of scientific inquiry and spiritual expression, especially in architecture and ornamentation.

The common geometric motifs found in Islamic art include the circle (symbolizing unity, eternity, and divine perfection), 8-pointed star (symbolizing light, guidance, and divine order), polygon (symbolizing balance, harmony, earthly and celestial realms), and the Arabesque (symbolizing the flow of life and interconnectedness).

In religious architecture, these patterns serve as a spiritual language that reflects divine unity and cosmic order. Geometric patterns also guide the layout of courtyards and prayer halls, evoking an emotional connection to something greater.

Some of the key symbolic concepts include:

We cannot discuss sacred geometry without mentioning the golden ratio. This mathematical concept, often symbolised by the Greek letter phi and approximated as 1.618, was first defined by Euclid (300 BCE) in his work Elements.

However, the most commonly known conception of the golden ratio is Leonardo da Vinci's illustration, the "Vitruvian Man," which explores its aesthetic and spiritual significance in art and architecture.

Doorways and portals are not only functional but also serve as transitional thresholds between the secular and sacred worlds.

Gothic cathedral doors are often elaborately decorated with carved figures of saints and biblical scenes to prepare visitors for the sacred space beyond.

Similarly, Islamic architecture features the calligraphy of Quran verses, while Buddhist temples may feature guardian figures flanking the doorways.

The narthex is another example of transitional spaces in sacred architecture. In early Christian and Byzantine basilicas, the narthex served both liturgical and social functions.

As Christianity evolved, the narthex became more enclosed and lavishly decorated, a place to pause, pray, and prepare the spirit for worship.

Sacred architecture shows us that spaces can communicate meaning without words. They can guide behaviour, evoke emotion, and create memories through light, form, texture, colour, and patterns.

This is what experiential design is about. When we design intentionally, our spaces become more than the sum of their parts—they become an experience.

Here are today’s key takeaways:

Next time you visit any religious building—whether it's a historic cathedral, local church, mosque, synagogue, or temple - take five minutes to observe the architectural details.

Even modern religious buildings often incorporate these ancient symbolic elements. You'll start to notice the architectural language that has been speaking to us for millennia.
