Sonera Stadium (until August 2010 Finnair Stadium; also known as Töölön jalkapallostadion, "Töölö football stadium") is a football stadium in Helsinki, Finland. The stadium was inaugurated in 2000. It has a capacity of 10,770 spectators. In July 2006, a new artificial turf with a FIFA two star rating was installed, replacing a first-generation artificial pitch used for the two previous years. It is located next to the Helsinki Olympic Stadium. Before the current stadium was constructed, it was known as the Helsinki Football Grounds and hosted some of the football preliminaries for the 1952 Summer Olympics.
It is the home stadium of HJK, and is also used for some friendlies by the Finnish national team. It hosted the final of the 2003 FIFA U-17 World Championship. The stadium was named as one of the stadiums that host the 2009 UEFA Women's Championship. For that tournament, the artificial turf earlier covering the field was replaced with grass.
