Before Christopher Columbus's Spanish fleet took over in 1492, the island of Hispaniola (which the Dominican Republic shares with Haiti) was ruled by the Tainios. The Spanish left a lasting impression on the country's culture, most notably as Spanish remains the official language today. After a little interference from the French who threatened Spanish control, the Dominican Republic finally gained independence in 1884. Rio San Juan's favourable coastal location meant that over the years it provided work for its inhabitants as one of the country's most important sources of fish.
For a real slice of Rio San Juan culture on your holiday, head down to Calle Sanchez, the base for the fishermen's daily business. Barter with the pescaderos for some freshly caught fish, or head down to one of the local restaurants where seafood is always top of the menu. To see the Dominicans in their partying element, then keep your eye out for the Merengu' beat, a type of fast jazz music which is hugely popular throughout the region. As for sports, any holiday in Dominican Republic holiday would not be complete without a trip to watch the baseball, their other passion, which is worthwhile for the atmosphere alone.
