Juan Esteban Manrique de Lara y Cardona, 3rd Duke of Naxera (1504-1558) was a Spanish diplomat. In 1543, he was sent to the court of King Henry VIII of England in London, and he was entertained by Henry Howard, Earl of Surrey (seeing the Tower of London and the swans along the River Thames), before being brought to meet with King Henry. He spoke of the marvels of the River Thames and the circus show that Surrey brought him to, and he was also impressed by Princess Mary of England's ability to speak Spanish.
