The Dominican Republic (not to be confused with Dominica, which is a much smaller Caribbean country) occupies more than half of the island of Hispaniola, the rest belonging to Haiti. It was colonised by Columbus, and Santo Domingo has been the capital since 1496. Consequently, some of the oldest European buildings in the Americas are in Santo Domingo.
Tourism is a big part of the economy, and many visitors see only the beaches. Caribbean beaches are great, of course, but you already know what they look like, so here are some pictures of Santo Domingo instead.
