Housed in the city's infamous former prison, this maritime museum complex details the region’s history from its most influential aspect—the sea. There are ship models and accounts of explorers who traveled to Antarctica, plus marine-themed artworks of Argentina. Lower levels trace Ushuaia's past as a penal colony, with a look at jail cells, items crafted by the resident convicts and stories of the more famous people incarcerated here. Twice-daily tours are available. Note to all Instagrammers: Photography is a no-no.
