It is known as the "Capital of Poetry", by virtue of being the birthplace of poet Carlos Drummond de Andrade, is part of the Circuit of the Gold and of Estrada Real.

The first settlements at the site date to the early eighteenth century, when the village of Itabira do Mato Dentro was founded by bandeirantes seeking gold. Itabira was politically emancipated as a municipality on 9 October 1848, through Provincial Law No. 374.

The highest point in the city is 1,672 meters above sea level, and is known as Alto da Mutuca. Itabira is an access point for a number of smaller cities, such as Jaboticatubas, Santa Maria de Itabira, Itambé do Mato Dentro and Nova Era.

Itabira is a regional economic center, and hosts a thriving iron ore extraction operation headed by Companhia Vale do Rio Doce since 1942, when the company was created by President Getúlio Vargas specifically for the mineral exploration of the Rio Doce valley. As of 2017, it is the second largest mining company in the world, and a considerable part of its iron ore output comes from the mines at Itabira. As a result of the decades-old extraction operations, the city faces air pollution problems.

In Carlos Drummond de Andrade's poem "Confidência do Itabirano," the speaker remarks:

"Tive ouro, tive gado, tive fazendas. Hoje sou funcionário público. Itabira é apenas uma fotografia na parede. Mas como dói!"

"I had gold, I had cattle, I had farms. Today I'm a public servant. Itabira is just a photograph on the wall. But oh, how it hurts!"
