Answer: On July 8–9, 2006, Pope Benedict XVI traveled to Valencia, Spain, to preside over the Fifth World Meeting of Families. It was his first visit to Spain as pope, marked by a large outdoor Mass at the City of Arts and Sciences and a Vatican postmark dated 07.08.2006 commemorating the event. The trip emphasized the importance of family life — and also inspired a commemorative Vatican stamp issued on November 20, 2007.
