Musa embarked on a large building program, raising mosques and madrasas in Timbuktu and Gao.
Most notably, the ancient center of learning Sankore Madrasah (or University of Sankore) was constructed during his reign.

In Niani, Musa built the Hall of Audience, a building communicating by an interior door to the royal palace.
It was "an admirable Monument", surmounted by a dome and adorned with arabesques of striking colours.
The wooden window frames of an upper storey were plated with silver foil; those of a lower storey with gold.
Like the Great Mosque, a contemporaneous and grandiose structure in Timbuktu, the Hall was built of cut stone.

During this period, there was an advanced level of urban living in the major centers of Mali.
Sergio Domian, an Italian scholar of art and architecture, wrote of this period: "Thus was laid the foundation of an urban civilization.
At the height of its power, Mali had at least 400 cities, and the interior of the Niger Delta was very densely populated."
