The fate of the original lampstand from the Tabernacle is not known (What Happened To The Tabernacle?). Later, The Temple (see Temples) in Jerusalem during the time of Solomon had ten lampstands of pure gold, five on each side in front of the inner sanctuary (1 Kings 7:49, 2 Chronicles 4:7). These were plundered by the Babylonians when God permitted Jerusalem's fall in 586 B.C. (Jeremiah 52:19) (see Ancient Empires - Babylon, Why Babylon? and Temple Mount Treasures).
When the Jews were allowed to return from the Babylonian Exile, another lampstand was made. This one was carried away by the Romans under Titus when they conquered Jerusalem in 70 A.D. (see Ancient Empires - Rome and Fall of Jerusalem In 70 A.D.), and placed in their "Temple of Peace" in Rome. When Rome was plundered by Genseric in 455, he is said to have moved it to Carthage. When Carthage was retaken by Belisarius in 533 A.D., it was reportedly taken to Constantinople, and then later back to Jerusalem, where it finally disappeared.
Apart from its practical use inside the windowless Tabernacle, the menorah symbolized knowledge of God as a true light for a dark world.
