BossardArena

The BossardArena was not the first building on this patch of ground in Zug. The Herti Hall stood here for four decades before it was pulled down in 2010. The new structure opened that same August, but the name on the door has changed again. In May 2025, the venue became Oym Hall after the club's chairman acquired the naming rights for fifteen years.

The building sits on Generalguisaner Strasse 4. It is an indoor ice sports venue that replaced the old Herti Hall, which EV Zug used from 1967 until its demolition. The primary tenant has been the professional ice hockey team EV Zug since the 2010/11 season. The ground features an artificial ice surface.

The capacity has shifted over time. It started at 7,015 seats before being increased to 7,200 in summer 2017. Further expansion plans are underway to reach 9,000 seats. The women's team set a league attendance record with over 2,000 spectators in a match against HC Davos.

The arena hosts events beyond hockey. It held the 15th Swiss Music Awards in May 2022 and matches of the 2015 IIHF World U18 Championship, including a semi-final with 7,015 spectators. Tennis exhibitions featuring Boris Becker and Steffi Graf also took place here. The structure stands as a functional replacement for the old Herti Hall, designed by Scheitlin Syfrig Architekten and built by Anliker AG for the City of Zug.
