located at the end of Birgitte Gøyesvej down to Pøleåen (a stream running through the district of Ullerød) — due to the location, the field was hence nicknamed skråningen (English: the slope) or grusgraven (English: the gravel pit). Frederiksborg Slotssogn stood behind the construction of a new sports facility at Selskov Stadium, which opened in 1958, consisting of a couple of association football fields and a small changing room on a hill. The North Zealandian club moved to the stadium the same year. Selskov Stadium was expanded in 1977, when an old to nearby Gadevang was closed (moving the road from being an extension of Ødamsvej to becoming an extension of Selskovsvej) and three new association football fields were established close to Frydenborgvej. The expansion involved an area, that consisted of underground marsh lands and a water connection from Gribskov towards the lake at Frederiksborg Castle, which complicated the entire construction process. The increasing number of members and others, who used the stadium and its club house facilities, meant that the city council funded the construction of a new club house (opened in 1986), that was almost twice as big as the previous one. A self-management deal in 1989 between Hillerød G&IF and Hillerød Municipality resulted in the establishment of a new independent department on 1 January 1990 with the purpose of managing the sports facilities at Selskov Stadium, and funded by a yearly operating grant from the regional municipality. For several years, up until 1990, the athletic course in the southwest corner of the stadium had been used for motorcycle speedway races, often gathering attendances of up to 10,000 people, but new safety regulations and several noise complaints from neighbors resulted in this activity being moved to Slangerup. Speedway had worn out the running tracks at the athletic ground. When the local politicians declined to make a bid for the DGI's Landsstævne in 1998, a decision was made to instead invest DKK 15 million on new sports facilities, about half of the amount was to be used on Selskov Stadium, including the athletic ground at Selskov Stadium. A new athletic ground was inaugurated in 1997. At the same time, the club convinced the local politicians that the most important outdoor activities in the city would be placed at the stadium, which therefore changed its name to Hillerød Stadium. In 2005, Hillerød Municipality constructed a new association field, measuring 120x80
