José Castro Mendivil Digital Planetarium (Spanish; Castilian: link=no|Planetario Digital José Castro Mendivil), also known simply as the Morro Solar Planetarium (Spanish; Castilian: link=no|Planetario del Morro Solar), is a planetarium and site museum dedicated to astronomy in the Morro Solar of Chorrillos District, Lima, Peru. It is named after the engineer who designed it.[2]
It is administered by the Peruvian Astronomy Association (Spanish; Castilian: link=no|Asociación Peruana de Astronomía, APA), founded on August 15, 1946,[3] and then headed by Peruvian astronomer .[2] Besides its 360° theatre, it also features remnants of the Battle of San Juan during the War of the Pacific.[4]
The first stone was placed at 1 p.m. by Peruvian astronomer and head of the Peruvian Astronomy Association, during a ceremony that took place on February 19, 1954, three years after the Peruvian government granted the terrain for the building's construction.[2] It was formally inaugurated on April 23, 1960.[2]
In 1968, construction of an observatory began, with the Astronomical League of the United States donating a Schmidt–Cassegrain telescope. The building's iron dome was designed by the industrial service of the Peruvian Navy, with the entire complex having a cost of US$62,800.[2]
In 2013, a digital projector was added to the planetarium.[2] [5]
In 2018, the APA donated three bronze plaques to replace the ones stolen at the nearby Monument to the Unknown Soldier.[6]
