[1] The origins of this town cover a space of no more than 150 years, so much so that in his book, the Chilean historian Francisco Astaburuaga makes the first reference to the city, naming it as "Fundo Monte Águila".

[2][3] The history begins with the indigenous Mapuche and Araucanian people settled in the area of Monte Águila, belonging to the district (es:subdelegación) of Yumbel.

The trans-Andean railway, whose construction began in 1905, was funded by Porfirio Ahumada, a Chilean national, and his partners Corsini, Carlos Viel (engineer), Martin Worman and Horacio del Río.

This was a key event in the formation of Monte Águila, enabling the city to come together and achieve rapid growth, bringing with it social and cultural development.

Other catastrophes have affected the town recently, including a tornado in the nearby city of Los Angeles, and a large flood, due to heavy rainfall in July 2019.

Being part of Cabrero, they have the right to vote as citizens of the commune to choose their municipal authorities (1 mayor and 6 councilors), which are elected every four years.

[3] With the new administrative division, imposed by the dictatorial regime of Augusto Pinochet, Monte Águila remained as a suunity within the commune of Cabrero, being governed by a designated mayor until 1992, when at the end of the Military Dictatorship a municipal election was called.

In 1992, when at the end of the military regime, the first mayor to return to democracy Hasan Sabag Castillo (DC), who was in office until 2012, was called to municipal elections.

[15] Proof of this are the series of references that exist in the city to this transport, such as mosaics in the main square, murals, artistic representations, sports clubs, neighborhood councils (in Chile, juntas de vecinos), etc.

[15] Undoubtedly, the "Ferrocarril del Sur", the construction of the railroad that connected Monte Águila with the Argentine province of Neuquén and the increase in the productivity of the farms in the area gave life to this urban nucleus.

Today there is a Catholic church in Monte Águila, the "Nuestra Señora del Carmen" Chapel, which dates back to the end of the 19th century, when Monte Águila was nothing more than a small farmhouse with very few houses, being at the beginning of wood , and after an accident that caused a fire that destroyed it, the current cement construction that persists until today was made.

Most of the monuments of Monte Águila are located in the Main square, among which stand out a series of implements previously used in the railway industry, such as El Caballo de Agua and the Railroad Switch.

[31] In Monte Águila the most popular sport is football, which is mainly reflected in the existence of two clubs in the city “Ferroviarios de Chile” and “El Águila”, rival teams that play in the local football association to which they belong , which is the Bio-Bio Association (Yumbel) within the Asociación Nacional de Fútbol Amateur ANFA.

It should also be noted that Monte Águila has been the city of origin for soccer players such as Edgardo Abdala, Justo Farrán and Luis Chavarría.

[38][39] During the Fiestas Patrias, amateur car racing competitions, called piques ¼ de milla, are also held during the National Holidays period.

In recent times, this venue is occupied mainly for things outside the sport itself, such as events, such as La Cruz de Mayo or Ramadas, in Fiestas Patrias.

This coverage has evolved over the years, since until the early 1990s, only Televisión Nacional de Chile and Canal 13 could be tuned in, channels such as Mega, Chilevisión and La Red arriving later.

[53][54] There are also pay-TV services, being the most dominant in Monte Águila the companies Mundo Pacífico and TV Cable del Sur.
