The Tomb of Askia is a large mudbrick structure located in the ancient city of Gao, in present-day Mali. It was built in the 15th century by Askia Muhammad, who was one of the most powerful kings of the Songhai Empire.

The tomb is a rectangular structure with a flat roof, surrounded by a perimeter wall. It is decorated with intricate geometric patterns and carvings of Arabic script. Inside, the tomb contains the remains of Askia Muhammad, his wives, and other members of the royal family.

The Tomb of Askia is a UNESCO World Heritage Site and is considered to be one of the most important cultural landmarks in Mali. It is also one of the largest surviving examples of the Sudano-Sahelian architectural style, which is characterized by the use of mudbrick and decorative elements such as wooden beams and carvings.

Today, the Tomb of Askia is an important symbol of Mali's cultural heritage and a popular destination for tourists and visitors from around the world.
