Which Achaemenid king completed Persepolis’s Hall of 100 Columns?

Artaxerxes I completed Persepolis’s Hall of 100 Columns. This enormous audience hall, also called the Throne Hall, was begun under his father, Xerxes I, and finished during Artaxerxes’ reign in the fifth century BCE.

The hall formed part of the grand ceremonial complex at Persepolis, the Achaemenid royal center in southwestern Iran. Its name refers to the hundred columns that supported the roof, while monumental reliefs showed delegations bringing tribute to the Persian king. The building’s scale reflected the empire’s wealth and the court’s elaborate rituals.

Artaxerxes I ruled from 465 to 424 BCE. He is sometimes confused with Artaxerxes III, who later sponsored major building work at Persepolis. The hall was not the same structure as the Apadana, another audience hall at the site, whose completion is associated with Xerxes I.
