Ergani Indoor Sports Hall

The Ergani Indoor Sports Hall sits in Vyronas, a suburb of Athens, just off the main road near the entrance of the 'Theatro Vrahon'. The seating capacity is 320, comprising 220 permanent seats and 100 foldable ones, and the wooden parquet floor measures 18 by 36 metres. The hall is owned by the Municipality of Vyronas and serves as the home base for the local clubs Athinaikos A.C. and Enosis Vyrona.

The building opened in 2006 and was formally renamed in 2015 to honour Dimitris Kaltsas, an athlete and sports official. The club founded in 1917 has used the hall for decades, with their women's basketball team reaching the EuroCup final in 2010.

The venue is listed as one of the courts for the FIMBA World Championship 2027. The hall does not have its own website; information is managed through the municipality's portal.
