Momotombo is a stratovolcano in Nicaragua, not far from the city of León. It stands on the shores of Lago de Managua. An eruption of the volcano in 1610 forced inhabitants of the Spanish city of León to relocate about 30 miles west. The ruins of this city are preserved at León Viejo (Old León). It also erupted in 1886, 1905, and most recently November 30, 2015.
