Masada

Masada was a location in Judea (later Israel) involving a hill fortress. (PROSE: The Last Days, The Suns of Caresh) In the 1st century, it was the set of a siege, because of a Jewish revolt against the Roman Empire. The siege ended when all the Jews committed suicide. The First Doctor and his companions were involved in those events. (PROSE: The Last Days)

In 1972, during an archaeological dig, an anachronistic Spitfire was discovered under it. The Third Doctor and Jo Grant worked along with the local UNIT to solve the mystery. (PROSE: The Suns of Caresh)

The Eighth Doctor compared his destroying Gallifrey, which had been conquered by Faction Paradox, to what happened at Masada. (PROSE: The Gallifrey Chronicles)
