Santa Engracia is a national Pantheon and is very much reminiscent of Rome Pantheon interior with each chapel carrying a cenotaph of the most distinguished men in Portuguese history -– Henry the Navigator, Luis Camoes (a poet who earned the recognition after his death), Vasco da Gama, Pedro Alvares Cabral (the man who discovered Brasil), Afonso Albuquerque, Nuno Alvares Pereira. The cupola of white and pink marble and three half-cupolas formed by semi-circles are covered with rosettes which are repeated in the design of the marble floor. To the sides are entrances to several more chapels where you can see cenotaphs of Almeida Garrett (a writer), Amalia Rodrigues (a famous fado singer) and several military men. This is the largest baroque structure in Lisbon and it took almost 300 years to build it.

You can also take an elevator up five floors and a short flight of steps to the top of the cupola to get a panoramic view of the city and look at the floor designs and the cupola in more detail.
