Built atop a Roman forum, the Museu Nacional de Machado de Castro is a major source of pride for the Portuguese. Some parts of the forum are still visible while you can journey down to the dark crypto portico if you are in the mood for it. The museum has a wide array of artefacts. Once you enter the museum, you begin with the sculpturing section after which you are taken on an architectural trip and so on. Featuring pieces from all over the world, the museum has an entire reconstructed chapel in it and sixteenth century terracotta pieces.
