Carolina. The town was founded as El Roble and officially recognized by Spanish Governor Juan de Rivera in 1714. It was settled on the intersection of the
Piedras River and the Juan Méndez Creek (part of the
Puerto Nuevo River basin). The town eventually adopted the name of that river, ''Río Piedras'', and was proclaimed a municipality in 1823, when the city hall and ''plaza'' (main town square) were built.
During the nineteenth century, most of its territory was used for agricultural and livestock-raising purposes.

The ''Camino Real'', precursor to the Carretera Central, connected Río Piedras with Caguas and to southern Puerto Rico, was also built before the end of the century.
Its location along the ''Camino Real'' between the walled city of San Juan and the rest of the island turned Río Piedras into a commercial hub and junction between the Spanish colonial government and the rest of Puerto Rico.

Paseo de Diego
In July 1980, it was revealed by then Mayor Hernán Padilla, that Calle De Diego, one of the roads with the greatest commercial movement and traffic congestion in Río Piedras, would be converted into a Pedestrian Walkway in the following year. Padilla indicated that the construction of the Pedestrian Walkway, which would extend from the street Ferrocarril to Ponce de Leon Avenue, including a portion of Calle del Carmen, would cost around $1.5 million.
On December 5, 1981, the first phase of Paseo De Diego, built by Redondo Construction at a cost of $1,100,000, would be delivered to the Mayor of San Juan before December 18, the date of its official inauguration, four months before the original expected completion time. This would be possible despite the fact that the project had been carried out with the public passing through and shops open. It would have two ornamental fountains, four clocks, attractive light fixtures, and 42 trees that would complement the appearance of Paseo De Diego, which had all the details of a mall, but outdoors. It would officially inaugurate on December 18, of that year.

On November 5, 1983, located on the Paseo de Diego, a 90,000 square foot shopping center
Plaza de Diego Mall, would inaugurate with three levels. The first two levels would count with 13 stores, and the third would count with 13 food establishments. It would be developed by Plaza de Diego Shopping Center, Inc., and designed by Huyke, Colón y Asociados.
