Opened in 2012, this is a state-of-the-art interactive display telling the history of the city from its conquests by Romans, Arabs, and Crusaders to the golden age of discovery through to the "Carnation Revolution" of 1974. It aims to engage all the senses—you smell the spices brought back from the exotic east by Portuguese explorers, hear the hammers of cathedral builders and footfalls of marching troops. Central to the exhibition are the earthquake and tsunami that destroyed much of the city in 1755; it's still believed to be Western Europe's most deadly natural disaster. High-definition, wrap-around scenes and specially engineered flooring ensure visitors get an earthshaking experience. Fittingly, the museum is situated in the vast Terreiro do Paço square that was built on the riverfront after the quake destroyed the old royal palace that stood there. This is a fun, non-preachy way to discover the city's story with multilingual audio-guides lasting about a hour.
