Sportpark Höhenberg

The original venue opened in August 1921. Built by VfR Köln 04 rrh., the "VfR-Stadion" was a dedicated football ground with a capacity of 30,000. Between 1929 and 1931 it was converted into an athletics stadium as part of the city's green belt expansion and reduced to 18,000 places. It reopened as "Sportpark Höhenberg" on 20 September 1931 in front of 8,000 spectators for a match between VfR and Schalke 04.

For decades the terraces consisted of nothing more than grass embankments. A covered steel-frame stand for around 1,200 spectators was added in 1969, and the opposite side was later fitted with standing terraces. From the late 1980s a 3,000-seat stand was constructed, requiring the removal of the athletics track and a repositioning of the pitch — making it once again a pure football stadium. In 2012 the ground received a refurbished opposite stand and a floodlight system.

Following Viktoria's promotion to the 3. Liga for the 2019/20 season, the stadium was expanded to 10,001 places using additional temporary stands. The southern end gave rise to "Block 11", which quickly became the focal point of the club's organised fan scene. In 2021 a new pitch with undersoil heating and an LED perimeter board were installed. After the minimum capacity requirement for third-division stadiums was lowered ahead of the 2022/23 season, part of the steel-frame stand was dismantled, reducing capacity to its current 8,343.

Aside from Viktoria's home fixtures, the complex also serves as a training base: national teams from Tunisia, Japan, and France used it during the 2005 Confederations Cup and the 2006 World Cup, and Manchester United trained here in August 2020. Since 2016 the ground has also hosted rugby union internationals, with Germany's match against Spain on 19 March 2016 — attended by 6,214 spectators — marking the first such event.
