Panteão Nacional is a national monument and final resting place of notable Portuguese figures. It is located in the Alfama district of Lisbon, Portugal.

The building was originally built as the Church of Santa Engrácia in the 17th century, but it took over three centuries to complete the construction. In 1910, after the establishment of the Portuguese Republic, the church was converted into a pantheon to honor important Portuguese figures. It was officially inaugurated as the Panteão Nacional in 1966.

Some of the notable figures buried in the Panteão Nacional include poets Fernando Pessoa and Luís de Camões, former presidents of Portugal Manuel de Arriaga and Teófilo Braga, and fado singer Amália Rodrigues.

The interior of the Panteão Nacional is a magnificent example of baroque architecture. It has a large central nave, with six side chapels, each one dedicated to a different saint. The dome is decorated with colorful frescoes and there are marble sculptures throughout the church. Visitors can climb to the top of the dome to enjoy panoramic views of the city.
