Port Adelaide was forced to find a new ground to operate from. It was decided that the club would use Alberton Oval for the 1880 season. On 15 May 1880, Port Adelaide played its first match at Alberton Oval. The following year, the decision was made by the club to start leasing the oval from the Port Adelaide Council for the sum of 10 shillings a year. The oval is also used for training purposes for both AFL and SANFL operations, aside from 1997 through 2001 when SANFL training temporarily moved to Ethelton. In 1975 and 1976, Port Adelaide was temporarily locked out of the ground following a dispute between the Port Adelaide Council, the SANFL and the Club over seating arrangements at the ground. The club usually split its seating revenue 50/50 with the SANFL during this time period, an arrangement the SANFL held with each club. However, the Port Adelaide Council wanted to take 50% of all game day revenue, leaving the remaining half to the two to split between themselves. In 1975, the SANFL refused to accept the offer for the ground provided by the council, resulting in the temporary suspension of Port Adelaide's lease on the ground. This prevented Port Adelaide from playing any games at the venue and, the following year, training at the venue. With the 1977 season pending, the issues between the council and the club were resolved and the club was permitted to return that year. The ground possesses two notable grandstands named after individuals important to the club. The Fos Williams Family Stand is the oldest remaining structure at Alberton Oval, first constructed in 1903. The other grandstand, the Robert B. Quinn MM Grandstand, was first opened in 1972. The ground also has the bordering Allan Scott Power Headquarters for the administration of Port Adelaide, which opened in 1999 and is named after the club's initial major sponsor. Football Park (1997–2013) Port Adelaide first played at Football Park on 15 June 1974. Despite not being officially recognised as a 'home ground' in the SANFL, it hosted night matches for every team, as well as all finals between 1974 and 2014 regardless of 'home' team. During 1975 and 1976, Port Adelaide sold some of their home games (to be played at their temporary home, Adelaide Oval) to Football Park. Upon the club's entry to the AFL, fellow South Australian club was already
