Originally when the Bet HaMikdash was built – the Supreme Court of Israel, the Sanhedrin, convened in the Lishkat HaGazit, the Temple Square for the Non-Kohen (Ezrat Israel) …
when our situation deteriorated and the Sanhedrin was exiled it went from place to place – ten different places until their last place of meeting, which was in Tiveria.
Since then there has not been a Sanhedrin.
It is our tradition that the Sanhedrin will reconvene in Tiveria prior to returning to the Temple Mount.
Mishneh Torah, Sanhedrin Chapter 14:12
