MADRID, Sept 20 (Reuters) - Spain's Prado Museum on Tuesday published a list of 25 artworks seized during the 1936-39 civil war and under Francisco Franco's dictatorship, and announced a research project that could lead to the works being returned to their legitimate owners.
Among the works are paintings by 17th century Flemish artist Jan Brueghel the Younger and Spanish impressionist Joaquin Sorolla, according to the list.
The findings of the research, to be led by senior professor and expert on cultural heritage and the Civil War Arturo Colorado, are expected by early 2023.
More than half a million people died during the Spanish Civil War and an estimated 150,000 were killed later in repression by Franco's 1939-75 dictatorship, historians estimate.
One of the capital's most famous landmarks, the Prado contains over 7,000 of the world's finest paintings and other works of art.
