Obelisk of Aksum (Rome-returned)

Obelisk and Pillar

Description

Obelisk of Aksum (Rome-returned) is an obelisk and pillar in Ethiopia, Africa. UNESCO World Heritage List: Aksum gives its chronology as “c. 4th century CE; returned from Rome 2005.” Its listed material is Nepheline syenite. Listed figures include a height of 24 m and a heaviest stone of 160 tonnes (estimated). UNESCO World Heritage List: Aksum also records: “Royal stele.”

A 24 m stele taken to Rome in 1937 and returned to Aksum in 2005.

What makes it extraordinary

Physical Composition and Scale

The Obelisk of Aksum is a 4th-century CE stele carved from a single, solid block of phonolite, a weather-resistant stone similar to granite. It stands 24 meters (79 feet) tall and weighs approximately 160 tonnes (180 short tons). Despite its common name, it is technically a stele rather than an obelisk because it lacks a tapered or pointed top, instead terminating in a semi-circular peak that was historically enclosed by metal frames.

Architectural Ornamentation and Purpose

The stele features elaborate carvings including two false doors at its base and decorations resembling multi-story windows on all four sides. These intricate designs were characteristic of the largest Aksumite grave markers, which served as indicators for underground royal burial chambers. While hundreds of smaller, roughly carved steles exist in the Aksum fields, only the most prominent royal markers received such detailed architectural ornamentation to distinguish them from the markers of lesser nobility.

Removal and Transport to Rome

During the Italian occupation of Ethiopia in 1937, the monolith was taken as war spoil. To facilitate transport, the monument was cut into three pieces and moved by truck along a difficult route from Aksum to the port of Massawa, a process requiring five trips over two months. It arrived in Naples via the ship Adwa on March 27, 1937, before being reassembled and erected in Rome's Porta Capena square to commemorate the fifteenth anniversary of the March on Rome.

Air Freight Repatriation Logistics

The return of the stele in 2005 required significant infrastructure upgrades, including lengthening the runway at Axum Airport to accommodate large cargo planes. The three sections were transported from Rome's Leonardo Da Vinci International Airport using an Antonov An-124. The middle piece, returned on April 19, 2005, was described as the largest and heaviest piece of air freight ever carried at that time. The entire operation cost the Italian government approximately $7.7 million.

UNESCO-Led Reinstallation Project

The final reassembly of the monument in Ethiopia began in June 2008 under the supervision of a UNESCO-selected team led by Professor Giorgio Croci. The project required pouring a new foundation near King Ezana's Stele, which was also structurally consolidated during the process. The Obelisk of Axum was officially unveiled in its original home on September 4, 2008, marking the conclusion of a complex international effort to restore the monument to its historical context.

Seismic and Lightning Protection

During its 2008 re-erection in Aksum, engineers replaced the 1937 steel reinforcement bars with eight aramid fiber (Kevlar) bars to join the three sections. This modern material choice was intended to provide structural resistance against earthquakes, as Aksum is located in a seismic zone. Furthermore, avoiding steel prevents the monument from acting as a lightning magnet, a necessary precaution after the stele suffered considerable damage from a lightning strike while standing in Rome in May 2002.

3D Laser Scanning Documentation

In 2006, the Axum Stelae Field, including the returned obelisk, was documented using terrestrial laser scanning by the Zamani Project. This initiative creates high-precision 3D historical records of cultural heritage sites to ensure their virtual preservation. The project transformed point cloud data into textured models, providing a precise spatial record of the monument's condition shortly after its return to Ethiopia and prior to its final re-erection in the Northern Stelae Park.

Decades of Diplomatic Negotiation

Although Italy agreed to return the stele in a 1947 UN agreement, the monument remained in Rome for over 50 years. Repatriation was delayed by technical difficulties and high costs, leading to controversial claims that Emperor Haile Selassie had gifted the monument to Rome in 1961 to renew friendship. Successive Ethiopian governments, including the Derg regime and the post-1991 administration, continued to demand its return, eventually securing a positive commitment from Italian President Oscar Luigi Scalfaro in 1997.

Causes of Ancient Collapse

Archaeological evidence suggests that many Aksumite steles fell over centuries ago due to a combination of factors. These include structural collapse shortly after erection—as seen with the 33-meter Great Stele—seismic activity in the region, and military incursions by Imam Ahmad Ibrahim during the 16th-century Ethiopian–Adal War. By the 19th century, only King Ezana's Stele remained standing among the three major royal monuments, as documented by early European travelers like Henry Salt and Mabel Bent.
