The largest and lowest Central American country, Nicaragua  is a nation of geographical superlatives. Located at the elbow where the Central American isthmus bends and then plummets southward to Panamá , Nicaragua is almost dead center between North and South America.
Part of a biological corridor that for millions of years has allowed plant and animal species from two continents to mingle, it boasts an extraordinary blend of flora and fauna .
In the 16th century, Nicaragua’s geographical beauty  enchanted the conquistadores, who reported, “The Nicaraguan plains are some of the most beautiful and pleasant lands that can be found in the Indies because they are very fertile with mahicales and vegetables, fesoles of diverse types, fruits of many kinds and much cacao.”
Nicaragua is roughly triangular in shape and dominated by two large lakes in the southwest. Its 530-kilometer-long, northern border with Honduras , the longest transect across the Central American isthmus. To the south, the southern shore of the Río San Juan  defines the better part of the Nicaraguan–Costa Rican border. Wholly within Nicaragua, the San Juan has been a continual source of conflict with Costa Rica  to this day, whose attempts to navigate and patrol the river have been met aggressively by the Nicaraguan government.
To the east and west lie the Caribbean Sea and the Pacific Ocean, respectively. With 127,849 square kilometers of land area, Nicaragua is approximately the size of Greece or the state of New York. But Nicaragua has lost some 50,000 square kilometers to her neighbors over the past several centuries: the eastern third of what is now Honduras, as well as the now–Costa Rican territories of Nicoya  and Guanacaste , plus the Caribbean island of San Andrés.
Administratively, the nation is divided into 15 units called departamentos, and two vast autonomous regions on the Atlantic coast known as the North and South Atlantic Autonomous Regions (RAAN and RAAS). The departments, in turn, consist of 145 municipalities. The two autonomous regions elect their own officials on a separate electoral calendar. Nicaragua’s three largest cities are Managua , León , and Granada , followed by Estelí , Masaya , and the remaining department capitals.
