Career
In 1967, after the Six-Day War, Merioz was the first Jew to settle in the Old City of Jerusalem. Immediately upon his arrival to the Jewish Quarter, Merioz worked on salvaging the remains of the synagogues bombed by the Jordanians during the war. The remains were displayed at a museum he established on Hayehudim Street #1.
Among the most important remains were from the Hurva Synagogue.
Merioz later established the Blue and White Art Gallery, located in the old Roman Cardo in the middle of the Jewish Quarter.
