LOCATION AND SIZE
A country occupying the eastern two-thirds of the island of Hispaniola (Haiti occupies the western third) between the Caribbean Sea and the Atlantic Ocean, the Dominican Republic has an area of 48,670 square kilometers, more than twice the size of New Hampshire. It has a total coastline of 1,288 kilometers (800 miles), and a border with Haiti of 275 kilometers (171 miles). The capital city, Santo Domingo, is located on the country’s southern coast.
The relief of the Dominican Republic is the most notable of the Antilles. As the Caribbean’s most geographically diverse country, the Dominican Republic is home to the region’s tallest mountain peak, Pico Duarte, as well as the Caribbean’s largest lake and lowest elevation, Lago Enriquillo. The island has an average temperature of 26 °C (78.8 °F) and great climatic and biological diversity. The country is also the site of the first cathedral, castle, monastery, and fortress built in all of the Americas, located in Santo Domingo’s Colonial Zone, an area declared as a World Heritage Site by UNESCO.
