Although the origin of the game of tennis is hotly disputed, it is safe to claim, however, that the first enclosed tennis courts were not to be found at the Tudor court, but on the Continent. It is generally accepted that the 15th century Burgundian and Italian courts served as models for the early modern courts of Europe. Recreation and entertainment were essential forms of diversion in the life at court of the great Burgundian dukes Philip the Good and Charles the Bold as well as at the Renaissance courts of the illustrious Medici, Sforza, Gonzaga and Este princes. It should come as no surprise that according to archival research undertaken so far the Dukes of Burgundy and two Italian princely dynasties, the Estes of Ferrara and the Sforzas of Milan are associated with the first walled-in tennis courts that have been traced.
