Heritage Round was a round of matches in the Australian Football League in which all the teams wore guernseys from their past. The first Heritage Round was in 2003 and had been continuing every year until 2008.
The concept of the Heritage Round originated from the Centenary Celebration Round, which took place in 1996, in the centenary year of the VFL/AFL. As a tribute, the 8 original teams of the VFL played each other in Round 7, 100 years after Round 1 in the inaugural season. Essendon defeated Geelong at the MCG, while Carlton defeated Fitzroy, Collingwood lost to St Kilda, and Melbourne lost to Sydney.The remaining eight clubs played in their normal jumpers, as they came into the VFL/AFL at different times, not 1897.
The first Heritage Round saw Heritage guernseys worn by all teams except two. The Adelaide and West Coast Football Clubs (who played each other during the round) both had a short history had always used a variant of their original jumper throughout their existence. It was seen in a very positive and nostalgic light, especially as Brisbane wore a Fitzroy Lions guernsey and Sydney wore their former South Melbourne guernsey. St. Kilda's guernsey got such a positive reaction that it became their Clash Guernsey from 2004 until 2006. Port Adelaide wore its SANFL Magpies "Prison Bar" guernsey from 1914 when the club was made Champions of Australia. This angered the Collingwood Football Club (who were playing Brisbane at the MCG) which argued that they were the only team in the AFL that could wear Black and White.
