After the Babylonian Exile, many Jews returned to Jerusalem. They came in relatively small numbers, not sufficient to occupy both the Eastern and Western Hills. It was not until the Hellenistic period that the Western Hill was occupied again.
In this drawing we see the rebuilt city of Jerusalem on the Eastern Hill with a smaller Temple on Mount Moriah. On the Western Hill we see the houses and walls that were destroyed by the Babylonians and were not repaired at this time.
This drawing is the fourth in a series of reconstructions of Jerusalem in the times of Kings David, Solomon, Hezekiah, Nehemiah and Herod the Great.
