Río Piedras

The largest health institution in the archipelago, the Centro Médico de Puerto Rico (Puerto Rico Medical Center), is also located within its limits. Named after the river that flows through it, the Río Piedras (stones river), the district was the downtown center of a former municipality with the same name that was merged into San Juan in 1951. • Illustration — Satellite view from Old San Juan historic quarter (upper left) in San Juan Islet to Isla Verde resort area (upper right) in the Carolina municipality with Río Piedras district visible (lower center), 2012

The district is named Río Piedras (stones river) after the Piedras River, which is within its territorial limits.

Sugarcane was one of the biggest crops throughout the town's history. The area where Río Piedras is located today was previously settled by the Taíno, and archaeological sites have been uncovered nearby in Carolina. The town was founded as El Roble and was 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, Pueblo de Nuestra Señora del Pilar de 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. Sugar cane, cotton and coffee were some of the goods produced during this era at the municipality. A road connecting Río Piedras to San Juan was built during this time, along with the first church, Iglesia Nuestra Señora del Pilar, at the site of the modern town plaza. 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. The University of Puerto Rico was founded in Río Piedras on May 12, 1903 with funds diverted from the former Escuela Normal Industrial (Normal Industrial School). The University of Puerto Rico, Río Piedras Campus, today one of the largest universities in Puerto Rico. The university was a central part of the commercial and residential development of Río Piedras. The University Botanical Gardens are also located in Río Piedras.

The municipality of Río Piedras became part of the capital city of San Juan on July 1, 1951, after the approval of Project 177 by the House of Representatives of Puerto Rico. Following the annexation of Río Piedras, the city of San Juan, quadrupled its former size, becoming the largest city in Puerto Rico. With a population of 143,989 in 1950, Río Piedras was the most populous municipality in Puerto Rico before its consolidation with San Juan. The last mayor of the municipality of Río Piedras was Ángeles Méndez de López Corver. The former downtown area of the municipality is today part of the barrio (district) of Pueblo in San Juan, more popularly known as Río Piedras Antiguo (Old Río Piedras) and Río Piedras Pueblo (downtown Río Piedras), and it still preserves its former city hall, town square or plaza, and its cathedral, Catedral de San Juan Bautista.

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. • Illustration — Paseo de Diego on inauguration day in 1981 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. • Illustration — Plaza de Diego Mall in 1984

The flag of Río Piedras consists of a yellow cloth with a wavy blue stripe. The stripe has small white stones crossing it, and symbolizes the river that gave its name to the former town. The yellow background represents the sun, progress, and the future.

The region is mostly flat due to its location in the Northern Coastal Plains of the island. The highest regions are located at the south, mainly in the Caimito and Cupey barrios. The Río Piedras (or Piedras River) which gives name to the area crosses the region.
