Widely renowned as Spain’s premier museum, Museo Del Prado possesses one of the finest art collections in Europe (18,000 works strong!). Velazquez’s Las Meninas, Mantegna’s Death of the Virgin, and Dürer’s Adam and Eve are just three of the highlights. You can peruse the Prado’s collection on its website, zooming in to examine secrets and intricacies. Perhaps it’s also a chance for art history lessons with the kids. —E.C.
