Aruba Must Sees - Oranjestad. Oranjestad is the capital and Aruba's only town of any size. It has a lively feel with a variety of restaurants, nightclubs, and casinos. Much of the architecture combines Dutch gables and baroque ornamentation with Caribbean colours like pistachio, ochre, pink, and aqua. The result is a sun-drenched gingerbread confection with a touch of theme-park squeaky cleanliness. This sign is seen in many places around the island and makes for a good photo op.
