Río Piedras is a busy area in San Juan. It used to be a separate town and municipality in Puerto Rico. In 1951, it became part of San Juan. Today, Río Piedras is made up of different neighborhoods called barrios, like Pueblo and Universidad.

The town was first started in 1714 and was called El Roble. It became an official municipality in 1823. Since 1903, it has been home to the main campus of the University of Puerto Rico. Because of this, many people call it Ciudad Universitaria, which means "University City." The old downtown area of Río Piedras is now known as the Pueblo barrio of San Juan.

What Does Río Piedras Mean?

The name Río Piedras means "Stone River." It is the name of a river that flows through the area. Río Piedras was also the name of the former municipality from 1823 to 1950.

Long ago, the Taíno people lived in the area where Río Piedras is now. Scientists have found old Taíno sites nearby. The town was officially started in 1714 by Spanish Governor Juan de Rivera. It was built where the Piedras River and the Juan Méndez Creek met. The town later took the river's name, Río Piedras. In 1823, it became a municipality, and they built a city hall and a main town square called a plaza.

During the 1800s, most of the land was used for farming and raising animals. Farmers grew crops like sugar cane, cotton, and coffee. A road was built to connect Río Piedras to San Juan. The first church, Iglesia Nuestra Señora del Pilar, was also built then. Río Piedras became an important trading spot because it was on the main road between San Juan and the rest of the island.

The University of Puerto Rico opened in Río Piedras on May 12, 1903. It used money from an old school. Today, the University of Puerto Rico, Río Piedras Campus is one of the biggest universities in Puerto Rico. The university helped Río Piedras grow with new businesses and homes. The University Botanical Gardens are also in Río Piedras.

Río Piedras Joins San Juan

On July 1, 1951, the municipality of Río Piedras became part of San Juan. This happened after a plan called Project 177 was approved. After Río Piedras joined, San Juan became four times bigger. In 1950, Río Piedras had 143,989 people, making it the most populated municipality in Puerto Rico before it merged with San Juan. The last mayor of Río Piedras was Ángeles Méndez de López Corver. The old downtown area is now part of the Pueblo barrio of San Juan. It is often called Río Piedras Antiguo (Old Río Piedras) or Río Piedras Pueblo. It still has its old city hall, town square, and cathedral.

The Paseo de Diego

In July 1980, the mayor announced that Calle De Diego, a very busy street in Río Piedras, would become a walking street. This new pedestrian walkway would stretch from Ferrocarril street to Ponce de Leon Avenue. It would also include part of Calle del Carmen. The project was expected to cost about $1.5 million.

On December 5, 1981, the first part of Paseo De Diego was finished. It cost $1,100,000. The walkway had two fountains, four clocks, nice lights, and 42 trees. It looked like an outdoor shopping mall. The Paseo de Diego officially opened on December 18, 1981.
