Ischelandhalle, Multi-purpose hall in the Altenhagen district of the city of Hagen.

The Ischelandhalle is a multi-purpose hall in the Sportpark Ischeland in Hagen's Altenhagen district, next to the Ischelandbach stream, the Ischelandteich pond, the Ischelandstadion and the Theodor-Heuss-Gymnasium. It is used almost exclusively for sport, mainly basketball, table tennis and handball. Since the 2010 extension its spectator capacity is 3145 seats.

The building opened in 1966 and initially held about 1,800 spectators. After a major renovation in 2010, the capacity was expanded to over 3,000 seats and the hall was equipped with modern technology.

Locals call the hall "die Ische". It has hosted the German standard dance championship twice in the late 1970s and professional boxing with René Weller in 1983. At the December 1988 Andreas Cup, Žalgiris Kaunas and Statyba Vilnius played here with Arvydas Sabonis and Šarūnas Marčiulionis.

The hall stands in the Sportpark Ischeland in Hagen's Altenhagen district, next to the Ischelandstadion, the Ischelandteich pond and the Theodor-Heuss-Gymnasium. The nearest tram and bus stops are a short walk away; drivers reach the site via the Ischeland road network. The main entrance faces the sports park, and the hall is used almost exclusively for sport, so check the event before travelling.

The hall's official name changed with its sponsors: after the 2010 expansion it was called ENERVIE Arena im Sportpark Ischeland for five years, then Krollmann Arena from 2018, before reverting to Ischelandhalle in 2023. Locals simply call it "Ische".
