The Imperial Crypt and Chapel is located beneath the monument. The crypt was built in 1972 to house the remains of Emperor Pedro I of Brazil (also King of Portugal as Pedro IV) and his wives,
Maria Leopoldina of Austria and
Amélie of Leuchtenberg. The crypt is consecrated as a Catholic
chapel, as demanded by the then-head of the
Imperial House of Brazil,
Pedro Henrique of Orléans-Braganza. He agreed to allow the transfer of the remains of his ancestors to the monument on the condition that the place be consecrated as a Catholic place of burial, with a Catholic altar where
Mass could be said. Pedro I and Amélie's remains were transferred from the
Royal Pantheon of the House of Braganza in
Lisbon; Maria Leopoldina's were moved from a mausoleum in the Convent of Saint Anthony in
Rio de Janeiro. File:Olhares sobre o Museu do Ipiranga 2017 041 (cropped).jpg|Pedro I's
