Palácio Duque de Caxias

Palácio Duque de Caxias is a military command building located in downtown Rio de Janeiro, featuring red and black granite exteriors with polished Brazilian marble flooring throughout. The structure rises across multiple levels and serves as headquarters for military administrative operations across different branches.

The building was completed in 1941 to replace earlier military headquarters from the colonial and imperial periods. Major military operations relocated to Brasília in 1971, reducing the palace's role as the main seat of military administration.

The main hall features a large stained glass window depicting a significant military battle, with bronze panels illustrating important moments in the nation's military story. These artistic elements reflect how the building celebrates historical events that shaped Brazil.

The building is centrally located in downtown Rio de Janeiro but is generally not open to visitors without special authorization, as it remains an active military headquarters. Those interested in tours should inquire about access possibilities in advance.

A remarkable collection of stained glass artworks decorates the tenth floor, illustrating battles from Brazilian military history. These detailed artistic creations remain little-known to visitors but showcase how the nation's military past is told through craftsmanship.
