Santurce is a district or barrio in San Juan, Puerto Rico. The name Santurce comes from Basque, and in that language it is written as Sant Urtzi , which literally translates to St. George. The original Santurtzi is a town near Bilbao, in Spain. It is the most populated "barrio" in Puerto Rico and one of the most densely populated areas of San Juan at 17,951.7 residents per square mile (6,931.2/km²). Geography
 
Santurce is bounded by the Atlantic Ocean in the north, with more than five km of beaches.
The topography is mainly flat with low hills toward the central areas and swampy areas to the south along Caño Martín Peña and to the east near the Laguna San Jose (San Jose Lagoon).

History
Originally settled by the native Tainos, the area later became home to a significant population of slaves of African ancestry who arrived from the neighboring Danish Virgin Islands. Due to the abundance of crabs found in the area, the district became commonly known as “Cangrejos” (the Spanish word for crabs). Throughout the centuries, the district continued to grow due to its location at the crossroads between San Juan and its southern suburbs.
In 1876, Pablo Ubarri, an engineer from the Basque Country region of Spain arrived on the island to help in the construction of a railroad system and a steam tramway between San Juan and the town of Rio Piedras trough the center of “Cangrejos” which prompted the gentrification of the district. Many years after his arrival he was granted the title of Count of Santurce by the Spanish Crown. With his newly acquired title and influence, the district was renamed after his title.
During most of the 1930s and up to the 1950s, Santurce along with neighboring district Miramar becomes one of the most vibrant areas of the capital. Today, the district is starting to see resurgence in importance and life as many business and local establishments such as bars, clubs, and restaurants have opened their doors to locals and tourists alike due to the importance of trade and tourism in San Juan.
