If this is what it is, here is a little more info. Sorry for the short version and quick translation with some cleaning up.

The forest stadium Homburg, used for soccer and track-and-field events in Homburg (Saar) with a spectator capacity of 21.813 places, of it 1,767 seats. Main user of the stadium is the FC 08 Homburg.

The Hauptkampfbahn stadium 1937-1974 was inaugurated on 14 and 15 August 1937 with a circle sport celebration, within whose framework a soccer game match was played against SSV Jahn Regensburg, as a so-called main combat course. The combat course should become the center of a large-scale athletic ground, whose implementation and goal was made possible by the Homburger at that time mayor and NSDAP Kreisleiter Jakob Knissel. The architect is Ludwigshafener Willy Schwilling. In 1974 the stadium was renamed Waldstadion Homburg. Structural alterations took place in 1986 and 1989.
