Qal’at al-Bahrain: A Millennia-Long Chronicle of Trade, Culture, and Civilization
Qal’at al-Bahrain, also known as the Bahrain Fort or Portuguese Fort, is a remarkable archaeological site situated in the heart of Bahrain. This UNESCO World Heritage Site offers a unique glimpse into the rich history, culture, and civilization that thrived in the region for millennia.
More to come…UNESCO Description of the World Heritage Site
Qal’at al-Bahrain is a typical tell – an artificial mound created by many successive layers of human occupation. The strata of the 300 × 600 m tell testify to continuous human presence from about 2300 BC to the 16th century AD. About 25% of the site has been excavated, revealing structures of different types: residential, public, commercial, religious and military. They testify to the importance of the site, a trading port, over the centuries. On the top of the 12 m mound there is the impressive Portuguese fort, which gave the whole site its name, qal’a (fort). The site was the capital of the Dilmun, one of the most important ancient civilizations of the region. It contains the richest remains inventoried of this civilization, which was hitherto only known from written Sumerian references.
UNESCO Justification of the World Heritage Site
Criterion (ii): Being an important port city, where people and traditions from different parts of the then known world met, lived and practiced their commercial activities, makes the place a real meeting point of cultures - all reflected in its architecture and development. Being in addition, invaded and occupied for long periods, by most of the great powers and empires, leaved their cultural traces in different strata of the tell.
Criterion (iii): The site was the capital of one of the most important ancient civilizations of the region - the Dilmun civilization. As such this site is the best representative of this culture.
Criterion (iv): The palaces of Dilmun are unique examples of public architecture of this culture, which had an impact on architecture in general in the region. The different fortifications are the best examples of defence works from the 3rd century B.C to the 16th century AD, all on one site. The protected palm groves surrounding the site are an illustration of the typical landscape and agriculture of the region, since the 3rd century BC.
Encyclopedia Record: Qal'at al-Bahrain
The Qal'at al-Bahrain, also known as the Bahrain Fort or Portuguese Fort, is an archaeological site located in Bahrain. Archaeological excavations carried out since 1954 have unearthed antiquities from an artificial mound of 12 m (39 ft) height containing seven stratified layers, created by various occupants from 2300 BC up to the 18th century, including Kassites, Greeks, Portuguese and Persians. It was once the capital of the Dilmun civilization and was inscribed as a UNESCO World Heritage Site in 2005.Additional Site Details

The Tropical Turn: Agricultural Innovation in the Ancient Middle East and the Mediterranean
Agricultural innovation in the ancient Middle East and Mediterranean was significantly influenced by the long-distance dispersal of seven cultivated plants from tropical-subtropical South Asia, including rice, cotton, citrus fruits, eastern cucurbits, lotus, taro, and sissoo tree. This study, based on an interdisciplinary synthesis of archaeobotanical, archaeological, ethnobotanical, and historical-philological evidence, reveals that these plants were introduced between the mid-fourth millennium BCE and early centuries CE via maritime routes through the Persian/Arabian Gulf, Arabian Sea, and Red Sea. Philological comparisons, such as Sanskrit kārpāsa (cotton) and Akkadian karpassu, along with archaeobotanical findings, indicate that cotton was cultivated in Assyria for royal-palatial use by the 8th century BCE and in Bahrain before the 9th century BCE. Rice, another significant find, migrated from South Asia to Mesopotamia, likely as a foodstuff for merchants, but its cultivation was limited due to irrigation constraints and competition with endemic crops like flax and wheat. The study also challenges previous assumptions about the absence of citrus fruits in ancient Mesopotamia, suggesting that citron (Citrus medica) was present by the second millennium BCE, though its identification remains debated.

3D Documentation Towards Heritage Conservation: A Rapid Mapping Approach Applied to Bahrain Forts
A novel integrated approach using UAV photogrammetry and portable systems has been successfully validated for 3D documentation of cultural heritage sites, addressing challenges related to accessibility and material diversity. This method, applied to the Fort component of Qal'at al-Bahraindemonstrates its potential for generating high-accuracy metric data crucial for conservation decisions. The study highlights the approach's repeatability and applicability across similar contexts, offering a sustainable solution for remote and onsite heritage documentation. This work contributes to advancing digital preservation techniques for complex archaeological sites.

P.V. Glob – og oldtidshovedstaden Dilmun på Bahrain og den danske Golfekspedition
The Danish archaeological expedition led by Peter Vilhelm Glob (1953–) uncovered the ancient capital of Dilmun and its surrounding harbor on Bahrain's north coast, a site now recognized as Qal’at al-Bahrain. This discovery, designated a UNESCO World Heritage Site, traces urban development from 2200 BCE to the construction of the Bahrain Fort in the 15th century CE. The expedition, initially a collaboration between Aarhus Museum and Aarhus University, expanded across the Arabian Gulf region, contributing foundational research still supported by Moesgaard Museum and regional institutions. Key findings include Dilmun's significance as a historical hub, with artifacts now central to national museums in the Gulf.

Remembering the Dead in the Ancient Near East: Recent Contributions from Bioarchaeology and Mortuary Archaeology
A multi-disciplinary approach integrating bioarchaeological data with traditional mortuary analysis reveals deeper insights into ancient Near Eastern burial practices and societal structures. The study, focusing on sites like Qal’at al-Bahrain, demonstrates that combining skeletal and dental evidence with cultural, historical, and textual sources provides a richer understanding of how societies remembered and commemorated the dead. Key findings include evidence of population movement, ethnic interrelationships, and the treatment of disabled individuals, such as a woman from Early Dilmun period Bahrain who was buried with elaborate grave goods despite physical disabilities. The research highlights the importance of cross-disciplinary collaboration to overcome historical gaps in mortuary interpretation.

Bermerkungen zer Datierung und Interpretation kassitischer Siegelthemen unter Berücksichtigung interaktiver Begegnungen mit der Dilmun Glyptik
New chronological standards for Kassite seals from the 15th century BCE have been established, revealing early origins of the First Group and providing insights into the dating of seal inscriptions. The study also highlights the cultural influence between Babylonia and Dilmun, suggesting that antithetical compositions from Dilmun glyptic may have served as models for the Second Group Kassite iconography. Additionally, defined attributes in both Dilmunite and Kassite glyptic are identified as code forms of the god Enki, offering a deeper understanding of religious symbolism during this period.
