The Mausoleum at Halicarnassus or Tomb of Mausolus was a tomb built between 353 and 350 BC in Halicarnassus for Mausolus, an Anatolian from Caria and a satrap in the Achaemenid Empire, and his sister-wife Artemisia II of Caria. The structure was designed by the Greek architects Satyros and Pythius of Priene.
