Answer:
The pillars of Aksum, also known as stelae, were large, granite obelisks that were erected in the ancient city of Aksum (now in Ethiopia). These stelae were highly decorated and carved with various images, symbols, and inscriptions.
The tallest and most famous of the stelae is the Obelisk of Axum, which stands at over 79 feet (24 meters) tall and weighs over 160 tons. It is thought to have been erected in the 4th century AD by the Aksumite king Ezana to commemorate his military victories.
The stelae were made from solid granite and were highly polished and decorated with intricate carvings, such as doors and windows, false balconies, and inscriptions in Ge'ez, the ancient language of Ethiopia. The carvings on the stelae were not only decorative, but also served as a way of recording important events and accomplishments, such as military victories or religious events.
The stelae were not just decorative monuments, but also had practical uses. They were used as boundary markers and as supports for large buildings, such as the ancient palace of the Aksumite kings. The stelae were also a symbol of the power and prosperity of the Aksumite civilization and continue to be a source of pride for the people of Ethiopia.
