I believe this marked the end of known Jewish presence in Jerusalem until the end of the Crusader kingdom around 1291.
The famous Nachmanides recorded around the end of the Crusader kingdom that 10 Jewish men could not be found in Jerusalem but had to be recruited from far away villages for proper prayers for his pilgrimage.
The excavations turned up a building that apparently was ruined by the earthquake of 1033, and like the "Palestinian refugees" today, the ruins were left there unrepaired 66 years later during the siege, and indeed to this day.
