It is located in a high-rise block that faces the elevated La Palma Bastion portion of the city wall of San Juan which, when observed from beyond, makes the building look taller than it is in reality.

Architect Francisco Roldán was commissioned in the early 1920s to design a high rise building that would house both the offices and production machinery for the newly established Puerto Rican magazine and El Mundo, which would become one of the most widely circulated newspapers in the island.

It was built by Frank B. Hatch and his firm, who were also responsible for several civic edifications of the time such as the Brambaugh School in Puerta de Tierra.

The building was inaugurated in 1923 and, in addition to the staff offices and machinery, contained communications facilities, archives and photography workshops for both publications.
