You can translate this as the 'coal yard', a name given by the Christian rulers, but the original one is Alhondiga Yidida (The new grain store). The andalusi alhóndigas were public buildings where merchants could stay and store their goods. This is the only one that is preserved in Spain. You'll be surprised by the magnificent entrance gate. Today it's the headquarters of Fundación El Legado Andalusí (Lagacy of Al Andalus).
