Río Piedras, Puerto Rico
Río Piedras, Puerto Rico is a populous district of San Juan, and former town and municipality of Puerto Rico, which was merged with the municipality of San Juan in 1951. The district today is composed of various barrios (these are the primary legal divisions of municipalities in Puerto Rico) such as Pueblo and Universidad. The historic town was founded in 1714 as El Roble, it was given municipality rights in 1823, and since 1903 it has been the home of the University of Puerto Rico's main campus, earning the popular name of Ciudad Universitaria (similar to college town) today. The downtown and historic center of Río Piedras is officially known as the Pueblo barrio of the municipality of San Juan. Name 
In addition to being the name of the barrio and district, Río Piedras (Piedras River) is also the name of a river that crosses the district. Río Piedras was also the name of the former municipality of Puerto Rico (1823-1950). 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 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. 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. Incorporation into San Juan 
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. 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. Symbols
