Palacio de las Dueñas, Casa de Salinas & Hospital de la Caridad

Seville already has a hard-to-rival beauty, but these historic houses will leave you even more impressed. The floral courtyard of the Palacio de las Dueñas is almost as impressive as the art collection inside, while Casa de Salinas, with its mosaic floors and 16th-century character, takes grandeur a step further. The Hospital de la Caridad's domed chapel may be the most resplendent sight of all, though. The baroque masterpiece still has frescoes and sculptures available to ogle at.
