Jail, court room – even a junk room. Over the years, the 17th-century Fort Zoutman has had quite a few roles. It’s Aruba’s oldest example of Dutch architecture, and was originally built to defend Oranjestad from invasion. The tower faced its toughest test in 1799, when it played a pivotal role in fending off an English attack. It’s got everything a colonial fort should have, from stout walls to heavy cannons.
