Museu Nacional da Imprensa

The Museu Nacional da Imprensa is the only live printing museum in the entire Iberian Peninsula, and it's been collecting since 1997 — making it one of the world's largest archives of printing press and graphic arts history. You'll find working presses spanning hundreds of years, and the whole experience is surprisingly hands-on and interactive. It's the kind of place that makes you appreciate every page you've ever read.
