At the creation of the Roman province of Judaea in the year 6 CE, its governors—holding the rank of a prefect until the year 41 and that of a procurator after that—took up residence in Herod's palace. In 66 CE, the Roman governor Gessius Florus set up a mass crucifixion of Jews, sparking the First Jewish Rebellion. Rebelling Jews entered and burnt the palace. Only the three towers remained partially standing. When the future Roman emperor Titus destroyed most of Jerusalem in 70 CE, he spared these and set up the camp of the Tenth Legion Fretensis in the area of the palace ruins, a camp which covered the entire Western Hill. One of the towers—a rebuilt Hippicus (or Phasael) Tower on its intact base—became known as the Tower of David. This was due to the fact that during the Byzantine Period, the Western Hill had been mistakenly identified as Mount Zion and the remains of the one surviving Herodian tower were presumed to be King David's palace.
