In 1958 two new courts were built at "Der Bleiche", today's Diemelufer. Since 1990, the Marsberg Tennis Club has had a new sports facility in the Diemelbogen Sports Center with 5 tennis courts and a spacious clubhouse. The tennis club is particularly concerned with the athletic training of young tennis players, who can make their first attempts at this sport through trial courses. A total of 7 teams currently participate in championships. 3 women's teams (Pönsgen games) and 4 men's teams (Mend games).
