Some geologists believe that over time, cataclysmic movements of the Earth created mountain ranges and diverted the river to its present course.

In 1685, the Bishop of Nicaragua and Costa Rica, Fray Ramon Rojas, died in Metapa (then called Chocoyos), exhausted after escaping from a pirate attack.

In 1856, Metapa was the base for the “Junta de Recursos” formed by Nicaraguan patriots to collect funds for creating the "Ejército del Septentrión" (Northern Army).

On February 20, 1920, Metapa changed its name to Ciudad Darío by a Decree of the Government of President Emiliano Chamorro.

Every January 18, his birth anniversary, people congregate at the house for poetry readings, dance performances, and other cultural activities.
