[1]: 3, 842  Morro Solar is notable for being a site of the Battle of San Juan and Chorrillos between Peruvian and Chilean forces in 1881.

[11] The sedimentary sequence has been mapped with appropriate notes on directions and dips of the strata, faults and dykes and the interpreting geological events.

[8] The new wild potato species, S. neoweberbaueri, collected by Augusto Weberbauer on Morro Solar, was named by Ludwig Wittmack in 1914.

It is a stone obelisk with a 22 m (72 ft) tall bronze plaque and is painted in olive green with a photo of a Peruvian soldier carrying the national flag.

Bronze plaques on the sides of the base along the path leading to the site are set in low reliefs which give the allegorical narration of the history of the heroic defense of Peruvian soldiers against Chilean attack in the battles of San Juan and Miraflores.

The museum has exhibits of modern and antique telescopes, meteorological models and pictures, civil rocketry artifacts, along with a variety of items found in the Morro from the Battle of San Juan and Chorrillos.

According to the controversy raised by the Mayor of Lima, the statue would interfere with the scenic view of the Morro Solar, a heritage monument, and hence should be shifted to some other location.

[19] The statue was formally consecrated by Cardinal Juan Luis Cipriani on the top of Morro Solar in 2011 when Pope Benedict XVI sent a message of greetings and blessings to the people of Peru.

[20] The hills surrounding the Morro Solar contain antennas which rebroadcast TV channels and some radio stations in Lima.

The transmitting station was installed with a NEC transmitter of 400W with one seg signal with live content provided by America TV.
