Yeah, they are a multi sport club. Also got a hockey team in the second or third tier.Complete Trivia: I've seen Hammarby play a couple of times at Xmas' over in Stockholm. Bandy, though, not footer. Good game to watch.
Hammarby football games are pretty fun to watch/attend as well and they draw arguably the biggest crowds in the country. Bit of dipper syndrome about them tho sadly.
