The club's first ground was the "Campo da Rainha" (Queen's Field), inaugurated in 1906 with an exhibition game against Boavista. The site was located near the residence of Monteiro da Costa and was the property of the city's horticultural society. Aided by his father, a horticultor by profession, Monteiro da Costa rented a portion (30 by 50 meters) of uncultivated terrain to create the first dedicated football pitch in the country. Later that year, the society's vivaria were transferred to another location, allowing Porto to increase the pitch area to match the sport's official dimensions. The ground had capacity for 600 people, including a VIP tribune, and possessed a changing room equipped with showers and sinks, a bar and a gym. The first match between Porto and a foreign team took place at the "Campo da Raínha", on 15 December 1907, when the hosts played Spanish side Real Fortuna.
