1. Domes and Minarets: The Connection Between the cities and religions and Symbolism
Domes in the mosques of this region (from Iran and Azerbaijan to Uzbekistan and Turkey) serve multiple functions simultaneously. Structurally, a dome distributes the weight of the roof evenly onto the walls and supporting structures. In many buildings, a double-shell system is used (an inner dome for spatial proportion and an outer dome for visual grandeur). Additionally, in hot and arid climates, domes help with air circulation, promoting ventilation and reducing heat. Symbolically, domes often represent the sky and the spiritual world in Islamic architecture. Prominent examples of this tradition can be seen in the historic mosques of Isfahan, Samarkand, and Istanbul.
Minarets also share common features throughout the region. Their primary historical function was to serve as a place for the call to prayer (adhan), and because they are visible from a distance, they help define the location of a mosque within the urban fabric. In Central Asia, such as in Bukhara, minarets are often tall and cylindrical. In Anatolia (Turkey), they are slender and needle-like, while in Iran, minaret architecture combines brickwork and tilework with geometric patterns. These variations demonstrate that shared architectural patterns exist alongside local interpretations.
2. Traditional Houses with Central Courtyards: The Link Between Climate and Family Culture
This architectural pattern is found throughout the ECO region, from Iran to Afghanistan, Pakistan, and other member countries. In this type of design, a central courtyard is surrounded by rooms on all sides, sometimes accompanied by iwans (semi-open spaces) on one or more sides. The courtyard functions as a microclimate, where the presence of water features and vegetation helps cool the air. In hot regions, rooms open onto the courtyard to benefit from natural light and ventilation. Socially, the courtyard serves as the center of family life, while the separation between guest and private areas helps preserve privacy, an important value in Islamic culture. This architectural model is directly connected to cultural values.
3. Tilework, Brickwork, and Geometric Patterns: The Union of Art, Mathematics, and Spirituality
This aspect is one of the deepest and most complex shared elements among ECO member countries. The use of turquoise, blue, and lapis lazuli colors in tilework in countries such as Iran, Uzbekistan, and Turkmenistan evokes the sky and spirituality. In brickwork, geometric arrangements increase structural strength, and the use of protrusions and recesses can create shadows and reduce heat. In some structures, highly complex designs have been achieved using only brick, without tile. In this tradition, aesthetics and function are considered simultaneously.
In certain architectural designs, light passes through geometric patterns, creating dynamic and moving shadows throughout the day. These geometric motifs are common across the region and are not merely decorative; they represent a fusion of art, science, and philosophy that shapes the spirit of the architecture. They symbolize cosmic order and the structure of the universe and are based on simple forms such as squares, circles, and multi-pointed stars. In Islamic art, geometry is often used instead of figurative imagery to express profound concepts, emphasizing order, mathematics, and infinity as symbols of the divine. The centrality in these designs pointed to unity. These patterns form a shared visual language across the diverse cultures of the region.
Overall, architecture in this region is not merely the construction of space; it is a direct reflection of a shared culture and worldview among its people.
