After the siege of Jerusalem, Hyrcanus faced a serious economic crisis in Judea, although the economic difficulties probably subsided after the death of Antiochus VII, since Hyrcanus no longer had to pay taxes or tributes to a weaker Seleucid Empire. The economic situation eventually improved enough for Hyrcanus to issue his own coinage (see below). On top of that, Hyrcanus initiated vital building projects in Judea. Hyrcanus re-built the walls destroyed by Antiochus. He also built a fortress north of the Temple called the Baris and possibly also the fortress Hyrcania.
