Emperor Rudolf II was particularly fond of tennis. According to documents preserved at the Archivio di Stato in Florence (of April 1585) he once played doubles at the court in Prague for two hours with Archduke Ernesto and on another occasion watched a match between the Duke of Braunschweig and Giulio Cesare Gonzaga against Don Giovanni di Pernstein and Count Antonio d’Arco. One of Rudolf’s courtiers, Adam Wallenstein Junior, wrote down the results of some of his tennis matches for 1604-1605. In September 1604 he played with Cardinal Alessandro d’Este and in August 1605 he won 360 toplars playing tennis. Two courts have retained their original exterior structure: Prague Castle and the Micovna at Opocno.
