The multifunctional hall, which is being planned by The Dome Betriebsgesellschaft outside of Frankfurt, is said to be in Hattersheim.
As several interlocutors familiar with the matter unanimously report, an area on the A 66 on the border with the western Frankfurt district of Sindlingen is earmarked for the project.
Among others, the Löwen Frankfurt ice hockey team and the United Volleys are to use the hall for their games.
Concerts and other events are also planned.
Mayor Klaus Schindling (CDU), who was re-elected on Sunday, could not be reached for comment.
Before the election, he had denied that the hall would be built in Hattersheim.
Schindling had confirmed that the investor had inquired about an area.
However, he did not know whether he had found anything.
A representative from The Dome declined to comment on the news.
In the course of the month you will comment on the future location.
competition to Frankfurt
The hall is in competition with a similar project in Frankfurt.
For years, the city of Frankfurt has been looking for a location for a new multi-purpose hall, in which the games of the lions, the volleys and the basketball team Skyliners can be played and concerts can take place.
However, the city had rejected the offer from "The Dome" to build such an arena next to the airport because it considered the location unsuitable.
She now favors a hall next to the Waldstadion.
However, the coalition has not yet agreed to this.
"The Dome" accuses the city of Frankfurt of having given the feeling of "not being interested in this completely privately financed project with great appeal".
That's why they looked around for a suitable location outside of Frankfurt.
The lions and the volleys had also accused the city of a lack of support.
