[4] The field was a piece of land behind the walls of the Parque del Buen Retiro in Madrid between the Frontón del Retiro and the now-extinct Pigeon Shooting Range, in which players who had left New Foot-Ball Club played some games before officially becoming Madrid FC on 6 March 1902, later moving to the esplanade next to the Goya bullring (now the Palacio de Deportes), a piece of land that is now the Campo de Jorge Juan.

The field was not fenced, so there was no separation between the players and the public, but it had a deep ditch around it to prevent the garbage carts pulled by oxen from accessing the pitch to dump waste.

The laundry and ironing of the kits were done in the house of Mrs. María and her son Casimiro, located next to the field, who left a room for the referee's night and provided a jar with water for the players to wash.

[citation needed] On 2 May 1903, coinciding with the commemoration of the Dos de Mayo Uprising, Athletic Madrid played their very first match between the 25 members that formed it, except for the treasurer Enrique Goiri who acted as referee.

[10] In 1912, Julián Ruete was elected president of the club and, given the increase in fans who wanted to see the team play, he built a new field.
