El Comercio Group (GEC) is a Peruvian media conglomerate that owns multiple newspapers, television stations and other entities.

[11] After the events, Miró Quesada commissioned his son Aurelio, engineer and manager of the newspaper, to seek financing to erect a new building in the same location.

Obtaining the funds was difficult as local banks did not wish to antagonise the "Patria Nueva" of Leguía, but Miró Quesada nevertheless acquired them and the new building began construction in 1921.

Architects Felipe González del Riego and Enrique Rivero Tremouille designed the new fortress-inspired building, and construction lasted three years.

The interior's crystal lamppost and iron gates (which feature the newspaper's initials and the caduceus, both imported from Belgium) were designed by Aurelio's brother Miguel.

Instead, a great lunch was organised by José Antonio Miró Quesada and his children in honour of the international journalists visiting the city for the ten-day centennial celebrations of the Battle of Ayacucho.

[11] The building's main hall served as the location of the wake of Antonio Miró Quesada de la Guerra and his wife María Laos, both murdered by a member of the Aprista Party in 1935.
