February 13th is UNESCO's World Radio Day, and here at Spanish National Radio, the day was celebrated with the broadcasting of a Ukranian Radio Station from Madrid and Barcelona. After taking a look at the act that took place at midday on Monday, we visit Madrid's Sorolla Museum, which recently begun a series of celebrations marking the 100th anniversary of painter Joaquín Sorolla's death with the exhibition 'Sorolla: Origins'... an exhibition museum curator, Blanca de la Válgoma, walks us through.
