This sprawling museum, sponsored by the French Tennis Federation, claims to house the world's largest collection of tennis memorabilia. Hidden underneath the Stade Roland Garros (site of the French Open), it also has an archive relating to the sport's 500-year history and hosts themed art and photo exhibits. If you're a serious tennis buff, the museum is worth the short walk from the metro station. Guided stadium tours (€10.50) are available in English on Wednesday and Friday through Sunday at 11 and 3, by appointment only.
