Partido de Nicoya

Map of the Partido de Nicoya and Guanacaste before the annexation to Costa Rica.

The Partido de Nicoya was a major part of what is now the Guanacaste province in Costa Rica. Originally the territory was bounded on the northeast by the La Flor river and Lake Cocibolca, or Lake Nicaragua, on the south by Costa Rica (Gulf of Nicoya, Tempisque River, Salto River), and on the east by a line that joins the northernmost part of the Gulf of Nicoya to the mouth of the San Juan River.
