Coffins of the Catholic monarchs, Royal Chapel, Granada, Sun 4 May 2014. A view of the crypt. The lead coffins of Ferdinand of Aragon and Isabella of Castile are at centre. Their marriage in 1469 united their countries, which make up 80% of modern Spain. They then conquered the Moorish kindom of Granada in 1492 and annexed it after expelling the Moors and Jews. The coffins at either side contain their daughter Joanna and her husband Philip the Handsome. Joanna lost her mind when he died and became known as Juana la Loca (Joanna the Mad).
