Nestled among the narrow medieval streets in historic Jeddah, the Othman bin Affan Mosque offers a rare, layered look into the city’s past. Fresh excavations at the site have revealed more than 1,300 years of continuous history, linking early Islamic foundations to global trade routes and evolving architectural traditions, the Saudi Press Agency reports.

The Othman bin Affan Mosque dates back to 33 AH (654 CE), making it one of the oldest archaeological and religious sites in Jeddah. Its historical significance is directly linked to Caliph Othman bin Affan, who designated Jeddah as the primary Islamic port. This decision turned the city into a major gateway for pilgrims to Mecca as well as a center of maritime trade.Situated along ancient paths and surrounded by traditional buildings, the mosque has been in continuous use for over 1,300 years. This uninterrupted use highlights not only its religious significance, but also its role in the everyday life of the city over the centuries.The mosque’s endurance reflects how Jeddah has evolved along with it, growing from an early Islamic settlement into a thriving port city that connects different regions of the world.
Layers of history in the major Islamic empires
Recent excavations have revealed that the mosque has several historical layers, each dating to the major Islamic periods. These layers confirm that the site remained active in:
- Umayyad Caliphate (661–750 CE/beginning 41 AH)
- Abbasid Caliphate (750-1258 AD)
- Mamluk Sultanate (1250–1517 CE/until 923 AH)
Overall, these periods extend from 41 AH (661 CE) to 923 AH (1517 CE), representing almost a thousand years of continuous development and use.During the Umayyad period, early coral-stone foundations and port-related development supported increasing numbers of pilgrims and traders. This was a time when Islamic rule expanded rapidly, spreading from Spain to India, and Jeddah began to establish itself as a major maritime centre.Under the Abbasids, often referred to as the Islamic Golden Age, the region saw advances in science, knowledge, and infrastructure. Evidence from the mosque, including glass lamps and aqueduct channels, suggests improvements in both mihrabs and water systems. These developments indicate that Jeddah was not only a trade center but also part of a broader intellectual and cultural network across the Red Sea.The Mamluk era brought further changes. The Mamluks, known for their military strength and control over trade routes, strengthened Jeddah’s fortifications. Discoveries from this period, including the import of ebony from Ceylon and ceramic fragments, point to increased commercial activity and long-distance trade. During this time the mosque developed as a flexible structure within a fortified and economically active port city.
Evidence of global trade and advanced engineering
One of the most important findings from the excavation is a sophisticated water system approximately 800 years old. The system reflects advanced engineering techniques used to manage water resources in coastal environments, indicating a high level of urban planning and technical knowledge.Equally remarkable are the rare ebony columns found in the mihrab. Scientific analysis has discovered these materials in ancient Ceylon, present-day Sri Lanka, providing clear evidence of Jeddah’s historical maritime trade ties in the Indian Ocean.The discovery of early Chinese porcelain among the thousands of artifacts recovered from the site has further strengthened this narrative. These objects confirm that Jeddah was part of a vast trade network connecting the Middle East to Asia.Overall, these findings show that the mosque was more than a place of worship. It serves as a point within a wider system of trade, travel and cultural exchange, reflecting the city’s importance on global maritime routes.

Architectural development in seven stages
The mosque has gone through seven distinct architectural phases, all of which are now digitally documented. This detailed documentation provides information on how the structure adapted over time in response to changing needs and influences.The construction techniques seen in these phases highlight traditional coastal construction methods, including:
- Use of coral stone as primary material
- Integration of wooden structural elements
- Design adjustments to suit humidity and coastal weather conditions
Each phase represents a stage in the mosque’s development, whether through expansion, repair or adaptation. These changes reflect both functional needs and the influence of different historical periods.Digital preservation of these stages ensures that the architectural history of the mosque is recorded in detail, allowing researchers and visitors to better understand its transformation over the centuries.
A living heritage site in modern Jeddah
Today, the Othman Bin Affan Mosque serves as both a place of worship and a cultural landmark. It has become a major destination on Jeddah’s cultural routes, attracting visitors interested in the city’s history and heritage.The site blends Islamic history with contemporary cultural activities, creating a space where the past is actively preserved while remaining relevant to the present. This approach supports broader efforts to preserve the architectural identity and historical heritage of the state.What makes the mosque particularly important is its continuity. It is not a relic that has been discarded or cast aside. Instead, it remains an active part of the city, carrying on a heritage dating back more than 1,300 years.
An ongoing story of faith, business and urban life
The discoveries at the Othman bin Affan Mosque offer a detailed account of the development of Jeddah. From its early days as a designated Islamic port to its role in global trade networks, the mosque reflects the city’s evolution over the centuries.From the coral stone foundation to the imported ebony and porcelain, each layer exposed adds to the story. It shows how religion, commerce and daily life merged in one place, shaping both the mosque and the city around it.In simple words, this place is a living record of history. It links early Islamic foundations with medieval trade routes and modern conservation efforts, making it one of the most important cultural and historical sites in Jeddah today.
