Aruba celebrates Flag Day, a national holiday. Claimed by Spain in 1499, Aruba became a Dutch colony in 1636. Still a Dutch possession, Aruba is a bit larger than Washington, DC. Oranjestad is the capital. Because it is located in the Caribbean Sea, the island has a tropical climate. However, it lies outside the hurricane belt and is seldom threatened. Slightly over 100,000 people live on the island, and many of them depend on the 1.5 million tourists who visit the vacation destination.
