the home stadium of OFI. The stadium is commonly known by its nickname, Yedi Kule ("Seven Towers" in Turkish). The historic ground of OFI was constructed in 1951 and after the death of the historic leader of the club it was named "Theodoros Vardinoyannis". The opening of the stadium took place on 11 November 1951 with the football game of OFI Crete with the team of Α.Σ.Δ.Α.Ν. (English: A.S.D.A.N.) (something like the current national team) and the result was a defeat for OFI, 4–1, a result that had a little meaning compared with the benefits that the Cretan club had won. At last, the largest Cretan club acquired its own "home", that would roof all the faithful of the new football ideals developed in Iraklion, Crete. The stadium was built on the ruins of a Christian and a Jewish cemetery and that in the area where the pitch is located, there were two big holes, remaining structures of German army guns from the World War II occupation. The highest attendance recorded at Yedi Kule is 12,391 for OFI's match against Olympiacos on 25 September 1988. OFI won the game 2–1. Supporters OFI has a big fan base in Crete.
