This wonderful science museum occupies a centuries-old former monastery converted by Pombal into the university’s chemical engineering building. With a couple of awards under its belt since opening in 2006, it features intriguing state-of-the-art interactive science displays coexisting with 18th-century lab sinks. Don’t miss the giant glowing globe in a room paved with medieval stones, or the psychedelic insect’s-eye view of flowers. Displays are English/Portuguese bilingual.
