[2] For the sesquicentennial anniversary of the battle, the Ministry of War of Peru decided to erect a monument to the combatants on the plain.

Through a public competition in 1968, the proposal for an obelisk made of marble by Spanish artist Aurelio Bernandino Arias was chosen as the winner.

According to the author, the work represents nearly half a century of struggle for freedom and American independence, from the Túpac Amaru II Revolution in 1780 to its victorious culmination at this location.

For the people of Ayacucho, the obelisk is part of the identity and pride of the Huamanga province and the department for being the place where Peruvian and South American freedom was achieved.
