In football, Olympiacos F.C. is the most successful football club in Greece, having won by far more titles than any other Greek football club, and its ground is at the Karaiskakis Stadium, in Neo Faliro. Ethnikos Piraeus F.C. had a longstanding presence in Super League Greece and also used the Karaiskakis Stadium as home ground, but in recent years the club has competed in lower divisions and currently plays home matches at the Helleniko Stadium, in Ellinikon. In basketball, Olympiacos B.C. is the only major club from Piraeus, one of the most successful at domestic and European level, and its home arena is the Peace and Friendship Stadium, while the volleyball department of the same club, Olympiacos S.C., is the dominant domestically and has made great success in European competitions as well. Piraeus rides really high in water polo, where Ethnikos Piraeus and Olympiacos departments have entirely dominated in Greece; the first is considered the "Emperor" of the sport and the latter is the only Greek water polo club to have been crowned European Champion.
