Goren repeatedly advocated or supported building a Third Temple on the Temple Mount from the 1960s onward, and was associated with various messianic projects involving the site. In the summer of 1983, Goren and several other rabbis joined Rabbi Yehuda Getz, who worked for the Religious Affairs Ministry at the Western Wall, in touring a chamber underneath the mount that Getz had excavated, where the two claimed to have seen the Ark of the Covenant. The tunnel was shortly discovered and resulted in a massive brawl between young Jews and Arabs in the area. The tunnel was quickly sealed with concrete by Israeli police. The sealed entrance can be seen from the Western Wall Tunnel, which opened to the public in 1996.
