The municipality of Larreynaga was founded by Colonel Manuel Ignacio Pereira Quintana on August 11, 1944. The town of Malpaisillo was officially declared a city in September 1968. It got its name "Larreynaga" from
Miguel Larreynaga, a Nicaraguan philosopher,
humanist, lawyer and poet. The municipality of Larreynaga is home to the
Cerro Negro volcano, just 10 km from the city of Malpaisillo. Cerro Negro has erupted frequently since its first eruption. The last volcanic activity at Cerro Negro occurred on August 5, 1999, and lasted for a total of two days. In recent years, the Cerro Negro volcano has been a popular destination for
sandboarding. ==See also==
