9. Stadion, Temporary public viewing area and fan camp in Liestal, Switzerland

The 9. Stadion was a temporary public-viewing arena and fan camp built between March and May 2008 on farmland between Bad Bubendorf and Liestal, part of Host City Basel for Euro 2008. It held 6,500 seats and 2,000 standing places, plus a Fancamp with 350 plots for about 2,000 overnight guests. The arena was a 1:5 scale replica of Berlin's Olympiastadion.

The 9. Stadion was a temporary public-viewing venue and fan camp built between March and May 2008 on farmland between Bad Bubendorf and Liestal for Euro 2008. The first sod was turned on 5 March 2008 and the site opened on 30 May 2008. Planned concerts by the Scorpions and DJ Bobo were cancelled for lack of demand, and the project ended with a loss of several million francs.

The name "9. Stadion" referred to a planned supplement to the eight Euro 2008 match venues. The site was also meant to host a cultural programme: a Scorpions concert on 5 June 2008 and a DJ Bobo concert on 27 June 2008 were both cancelled for lack of demand, while about 30 regional bands played to nearly empty stands.

The site lay between Bad Bubendorf and Liestal, about 100 metres from Bad Bubendorf station on the Waldenburgerbahn. The H2 main road over the Hauenstein pass ran directly alongside. During Euro 2008 an Autobus AG Liestal shuttle ran every 15 minutes, and the Waldenburgerbahn linked the area to Liestal and Basel.

The site was ordinary farmland before 2008; in summer 2002 it hosted the centre of the Eidgenössisches Turnfest, which drew over 70,000 visitors. The 9. Stadion was a 1:5 replica of Berlin's Olympiastadion, modelled on the Adidas World of Football of the 2006 World Cup.
