José Castro Mendivil Digital Planetarium (Spanish: Planetario Digital José Castro Mendivil), also known simply as the Morro Solar Planetarium (Spanish: 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: Asociación Peruana de Astronomía, APA), founded on August 15, 1946,^[3] and then headed by Peruvian astronomer Víctor Estremadoyro Robles [es].^[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, Víctor Estremadoyro Robles [es], 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]
