At the beginning of the 1990s, the Prime Minister of the Castilian provincial government paid an official visit to Israel. His host was Yitzhak Navon, who was the Minister of Education and Culture at the time. Navon later became the fifth president of the State of Israel. At a party for the Prime Minister of Castile, Yitzhak Navon gave a speech in his guest’s honor during which he mentioned Meir Ben-Dov’s research on Spanish synagogues. Mr. Navon noted that this research was invaluable to him when he went to Spain in order to do research for a film being produced by the Israel Broadcasting Authority to mark the five hundredth anniversary of the Expulsion.
