A new structural engineering study examining the historical site of Yeha in northern Ethiopia has revealed that the 2,800-year-old Grat Be’al Gibri palace possessed incredible structural strength, capable of supporting a building up to 16 storeys high.

The research focuses on Grat Be’al Gibri, a monumental palace site in Yeha dating back to the early first millennium BCE. Today, only the ground floor survives—a reality of preservation that has fueled decades of archaeological debate regarding the building’s original height.

Researchers Martin Drieschner and Mike Schnelle turned to advanced  modeling. Utilizing detailed archaeological data, the team constructed sophisticated three-dimensional simulations of two critical architectural elements: a wall corner and a doorway.

Because the precise material properties of millennia-old building components cannot be definitively recovered, the researchers tested a broad spectrum of possible stiffness and strength parameters for both the ancient stonework and the timber reinforcements.

The palace’s original construction relied on a meticulous mix of quarry stone, clay mortar, and horizontal wooden beams embedded within the masonry. This timber-reinforced technique formed systematic horizontal layers, a method distinct from contemporary building traditions in South Arabia.

Archaeological indicators had long pointed to a multi-level structure: podium walls measuring approximately 2.2 meters thick, ground-floor walls spanning 1.9 meters, a surviving southeast staircase, and an entrance framed by monumental stone pillars standing roughly 10 meters high. Previous virtual reconstructions had hypothesized a structure of eight floors—five full levels topped by three smaller tiers.

However, Drieschner and Schnelle’s simulations indicate that the ancient builders achieved an extraordinary structural safety margin.

Under fixed material values in the simulation, the wall corner model successfully supported a simulated load equivalent to 48 floors before failure, while the doorway model reached a capacity equivalent to 56 floors.

While the authors emphasize that these numbers do not imply the palace literally stood nearly 60 storeys tall, they demonstrate the immense spare load capacity engineered into the structure.

Even when subjected to worst-case stress scenarios—combining heavy loads with weakened material parameters—the models yielded load factors of 19 for the corner and 23 for the doorway. After applying standard engineering safety factors, both tested sections comfortably supported a 16-storey structure, doubling previous height estimations.

The study also identified the clay-mortared stonework as the primary determinant of structural performance. Variations in the ancient timber had a negligible impact on overall load resistance, whereas tension within the clay mortar layers constituted the main failure mechanism in the models.

The uniform performance of the tested wall sections points to an advanced, highly efficient system for weight distribution. The researchers note that if the builders had tapered the walls to be thinner on upper levels—a common architectural practice—the structural capacity of the lower storeys would have been amplified further.

Archaeological evidence indicates that Grat Be’al Gibri ultimately fell to a major, catastrophic fire. This new structural data confirms that ordinary operational loads could never have compromised the building’s integrity, reinforcing the conclusion that an extraordinary external event was required to bring down its mighty walls.

The findings offer fresh structural validation for the physical remains at Yeha, highlighting an elite level of pre-Aksumite engineering sophistication that reached far higher than modern science previously understood.

Ethiopia has been officially selected to host the 2027 Africa Commerce Convergence Summit (ACCS) in Addis Ababa, following a decision announced at the closing of the 2026 summit in Livingstone, Zambia.

The announcement was made by David Gowu, President of TICON Africa, during the landmark gathering, which brought together professionals from marketing, information communication technology (ICT), and supply chain disciplines from roughly 30 countries. The confirmation was met with enthusiastic celebration by the Ethiopian delegation.

Ethiopia’s successful bid was spearheaded by a collaborative coalition of three professional associations: the Ethiopian Marketing Professionals Association (EMPA), the Information Communication Technology Association of Ethiopia (ICT-ET), and the Ethiopian Logistics and Supply Chain Association (ELSA). These organizations will work closely with their continental counterparts to steer preparations for the 2027 event.

The ACCS serves as a strategic platform uniting three core continental bodies: the African Marketing Confederation (AMC), TICON Africa, and the African Supply Chain Confederation (ASCON). This convergence highlights how marketing, technology, and supply chain professions are increasingly intertwined and vital to driving Africa’s long-term economic development.

Gowu remarked that Ethiopia’s selection demonstrates the growing strength of its professional communities and its rising prominence in Africa’s commerce ecosystem. Fana Abay, President of EMPA, noted that this milestone will provide a vital platform to showcase the country’s multifaceted capabilities and foster deep-rooted connections with stakeholders across the continent.

The 2027 summit is expected to welcome thousands of professionals, innovators, business leaders, policymakers, and development partners from across Africa. The decision arrives as African businesses increasingly operate across borders under the continent’s broader push toward regional trade, integrated markets, and the implementation of the African Continental Free Trade Area (AfCFTA).

Diplomatic relations between Eritrea and Ethiopia have completely broken down after the Eritrean Ministry of Foreign Affairs announced the total severance of all bilateral ties. This drastic measure stems from a rapidly escalating diplomatic crisis triggered by Addis Ababa’s decision to shut down its embassy in Asmara and expel ten Eritrean diplomats.

This latest rupture follows an official statement issued by the Ethiopian government on October 1, 2026, declaring ten Eritrean officials—including the chargé d’affaires and diplomats accredited to the African Union—as persona non grata and ordering them to leave the country within a strict 48-hour deadline. Addis Ababa justified the directive by citing what it termed “direct and indirect acts of hostility and belligerence,” alleging that the targeted personnel had committed national security breaches violating the Vienna Convention on Diplomatic Relations.

In a sharp and immediate response, Asmara dismissed these justifications as entirely baseless. In a scathing official statement, the Eritrean Ministry of Foreign Affairs turned the tables on Ethiopia, condemning the expulsions and embassy closure as “unwarranted acts of hostility.” Asserting that Eritrea had long exercised patience and restraint to prevent a dangerous regional escalation, the government declared it had no alternative left but to reciprocate fully by cutting all diplomatic channels.

These escalating tensions are compounded by broader regional friction points, most notably Ethiopia’s strategic push for sovereign access to the Red Sea and competing security dynamics across the Horn of Africa. Asmara’s statement strongly accused Ethiopia of sustaining an active agenda of confrontation, alleging deliberate provocations and backing for opposition factions intended to destabilize the nation.
