After making Susa his administrative capital in 521 BCE, Darius I undertook significant construction projects to establish the city as a center of the Achaemenid Empire. His building works at the site included:

  • Fortifications: He restored the city's defensive walls.1
  • Apadana: He constructed a grand audience hall, known as an apadana.1
  • Residential Palace: He built a royal palace for his residence.1

Foundation inscriptions from the palace indicate that Darius sourced materials and craftsmen from across his empire to complete these projects. The palace area was later excavated by the French archaeologist Marcel Dieulafoy in the late 19th century.12
