Hamburg European Open

[1] The tournament is played on outdoor clay courts[2] at the tennis center Am Rothenbaum in the Harvestehude quarter.

WTA Hamburg was the location where Monica Seles, then-world No.1, was stabbed during a match by a disorderly local tennis fan on April 30, 1993.

[6] The German Open was a combined men's and women's tournament up until 1979 when the WTA event was moved to West Berlin.

Tournament officials sued the ATP in 2007 to stop the downgrade but a US jury decided in 2008 that it did not constitute a breach of monopoly laws.

[10][11] As the tournament stands now with its new position in the ATP calendar, it is an attractive event for many players who dislike playing on faster surfaces.

Its new position will prevent top-ranked players from playing there, since it is after Wimbledon and the focus moves towards preparing for the North American summer hardcourt surface before the start of the U.S. Open.

A new WTA Hamburg tournament was established in 1982, three years after the separation of the men's and women's German Open.

On April 30, 1993, Monica Seles, then-world No.1, was stabbed by a disorderly local tennis fan during a quarterfinal match with Magdalena Maleeva.

Hamburg returned to the WTA calendar in 2021 after it secured license in the 250 series from the Baltic Open that was previously held in Jūrmala, Latvia.
