In the background, one can see a group of houses with their roofs, with the Carmo church in the foreground. Above, against a blue background, one can see the imposing silhouette of the Itacolomi Peak, which in the past was used as a landmark by the first explorers. It represents the rich geological formations found in the region. At the center, one can see the statue of Joaquim José da Silva Xavier – Tiradentes, a monument by Virgílio
Casteré that was inaugurated on April 21, 1894 and represents the ideals of freedom of the Brazilian people.
