Who or what destroyed the Temple of Artemis?

The Temple of Artemis was a Greek temple dedicated to an ancient, local form of the goddess Artemis (associated with Diana, a Roman goddess). It was located in Ephesus (near the modern town of Selçuk in present-day Turkey). It was completely rebuilt twice, once after a devastating flood and three hundred years later after an act of arson, and in its final form was one of the Seven Wonders of the Ancient World. By 401 AD it had been ruined or destroyed. Only foundations and fragments of the last temple remain at the site.

In 356 BC, the temple was destroyed in a vainglorious act of arson by a man, Herostratus, who set fire to the wooden roof-beams, seeking fame at any cost; thus the term herostratic fame. For this outrage, the Ephesians sentenced the perpetrator to death and forbade anyone from mentioning his name; but Theopompus later noted it. In Greek and Roman historical tradition, the temple's destruction coincided with the birth of Alexander the Great (around 20/21 July 356 BC). Plutarch remarked that Artemis was too preoccupied with Alexander's delivery to save her burning temple.
