The Imperial Mausoleum, located to the right of the forecourt of the Cathedral of Saint Peter of Alcantara in Petrópolis, is the final resting place of the second Emperors of the Empire of Brazil, Pedro II and his wife Teresa Cristina, as well as their daughter, Princess Isabel, and other members of the imperial family of the second reign.

In Neo-Gothic style, matching the temple in which it is located, the Imperial Mausoleum is adorned with murals depicting the coronation of Dom Pedro II and his departure for exile upon the Republican coup on 15 November 1889.

[1][2] The mausoleum was inaugurated by President Getúlio Vargas in 1939, with the arrival of the remains of Emperor Pedro II and Empress Teresa Cristina.

They were repatriated from the Pantheon of Braganza at the Pantheon of the House of Braganza in Portugal in 1925, during the celebrations of the centenary of Dom Pedro II's birth; and were housed for a few years in the Metropolitan Cathedral of Rio de Janeiro, at that time the Church of Our Lady of Mount Carmel.

The remains of Princess Isabel and Count of Eu were interred there in the 1950s, repatriated from the Orléans Mausoleum in Dreux, France.
