Estadio Alfonso López, football stadium

Estadio Américo Montanini, formerly Alfonso López, is a football stadium in Bucaramanga with a capacity of 25,000. Its four stands surround a Bermuda 419 natural grass pitch, and the western stand includes a roofed section and press boxes. The stadium also has an electronic LED board in the northern area.

The stadium opened on December 12, 1941 and was originally named Unidad Deportiva Alfonso López Pumarejo after a Colombian president. Club Atlético Bucaramanga began playing home matches there starting in 1949, establishing it as the center of local soccer activity.

Since 11 June 2024 the stadium bears the name of José Américo Montanini, a Colombian-Argentine player and idol of Atlético Bucaramanga, after a survey run by Governor Juvenal Díaz on his Twitter account; the city's Olympic village took the name Hermán Aceros. Earlier attempts to rename it after Aceros, who died in 2018, had failed. Fans of the Leopardo fill the stands on match days.

The stadium sits in Bucaramanga, and the eastern stand has been slated for expansion since 2014, a project delayed by funding shortfalls and later shelved when the 2023 Women's World Cup went to Australia and New Zealand. Access is via the city's public transport or on foot; the venue has no roof over the western stand since the 1996 works removed its cover.

The stadium's name changed on 11 June 2024, when Governor Juvenal Díaz announced it would honor José Américo Montanini, a Colombian-Argentine player and idol of Atlético Bucaramanga, after a poll on his Twitter account. The city's Olympic village was renamed Hermán Aceros at the same time.
