Hospital de los Venerables, (home for elderly priests). Not a name that entices you to visit the place is it?
Its description in a guidebook hints that there’s more “A little gem of a museum/church/gallery.” And mentions that “To the left is a small room housing paintings from Sevillano painters, including Velázquez.”
Including Velázquez! I’d rewrite that phrase given The Metropolitan Museum says he’s “the most admired—perhaps the greatest—European painter who ever lived.”
