On the Galatian border, Archelaus possessed crystal and onyx mines. Archelaus transferred his palace from the mainland to Elaiussa Sebaste. After he and his family settled there, Archelaus developed the city. He built a royal residence, built a palace on the island in the harbor and he renamed the city in honor of Augustus. "Sebaste" is the Greek equivalent word of the Latin word "Augusta". Archelaus renamed a village, Garsaura, to Archelaïs, turning it into an administrative centre, which later became a colony under the Roman Emperor Claudius.
