August-Schärttner-Halle, Indoor sports and events complex in Hanau, Germany.

August-Schärttner-Halle is a multipurpose hall on the northern edge of Hanau, completed in 1989. It measures 116 m long, 77 m wide and 12 m high, with 3,000 m² of interior floor and a light blue roof carrying a photovoltaic array since 2014. Grandstands run along both long sides, one with fixed seats and one retractable, and a gallery with two counters and toilets circles above them, reached directly from the main entrance on the south side.

The August-Schärttner-Halle was completed and inaugurated in 1989 on Hanau's northern outskirts. It is named after August Schärttner, a Turner and revolutionary. In 2015 the hall sheltered up to 1,025 refugees for four weeks before the emergency accommodation moved to Hanau Housing on the former Pioneer-Kaserne site in the east of the city.

The name honors a gymnast and activist from the workers' gymnastics movement. Today the hall brings people together for sports competitions and concerts, shaping community life in Hanau.

Around 600 parking spaces are on an unpaved open area northwest of the hall. The main entrance on the south side leads straight onto the gallery level, where two counters and toilets are located. On weekdays the hall serves school sports from 8 am to 5 pm and club and company sports from 5 to 10 pm.

The building has solar panels on its roof since 2014 that generate energy for operations. This makes it one of the earlier sports venues in the region to embrace solar power on such a large scale.
