Alexandreion
Jericho Governorate, Palestine
Alexandreion (Greek), or Alexandrium (Latin), called Sartaba in the Mishna and Talmud and Qarn Sartaba in Arabic, was an ancient hilltop fortress constructed by the Hasmoneans between Scythopolis and Jerusalem on a pointy barren hill towering over the Jordan Valley from the west. It was likely named after Hasmonean king Alexander Jannæus (104–77 BCE).
