Heerenveen played at the Sportpark Noord. The club's training facilities are regarded as world class, which is said to be a major factor in their recruitment of younger players. The name of the clubs facilities is sportpark . The facilities are shared with VV Heerenveen and sc Heerenveen (women). Colours, crest and anthem The crest on the club emblem is the symbol of the flag of Friesland. The flag of Friesland is based on the arms of the 15th century. The stripes and seeblatt shapes represent the districts of Friesland. A unique tradition in the Dutch Eredivisie is that the Frisian national anthem is played and sung before every domestic match. UEFA does not allow this tradition in European matches. Nevertheless, the anthem is sung by the supporters anyway. Rivalry SC Cambuur Heerenveen retain a very fierce rivalry with SC Cambuur. One of the reasons of the rivalry is the short distance between the two clubs. Because of that the clubs often refer to each other as DKV which stands for Dertig Kilometer Verderop (Thirty Kilometers Away) so that they don't have to mention each other's names. However, the biggest and also the most confusing reason is the background of the clubs. Many people who aren't involved in the rivalry find it difficult to understand. Most of the Heerenveen fans are from small villages from the entire province (and even outside it) and are very proud of their Frisian identity. Since the 80's the club have been expressing this Frisian pride to the rest of the Netherlands. The Frisian flag, the Frisian anthem, all Frisian symbols were linked to the club, which made Heerenveen the face of Frisia. Because of this Cambuur slowly disappeared in the shadow of Heerenveen, as a reaction to this Cambuur fans started distancing themselves from the Frisian identity. Nowadays Cambuur don't consider themselves Frisian even though they are from the capital of the province. They now call themselves Leeuwarders aka people from the city. Heerenveen fans are mockingly called boeren (farmers) because Heerenveen isn't a city and the fans mainly live in small villages. Because of the successes of Heerenveen and the meager performances of Cambuur including almost going bankrupt, the rivalry was almost forgotten. When Cambuur got promoted back to the Eredivisie in 2013 by winning the 2012/13 season of the Jupiler League the rivalry got revived. Before the meeting on 29 September 2013
