South of Santurce is [[Hato Rey]], part of the former municipality of Río Piedras. Hato Rey was grazing ground for cattle owned by the royal government (hence its name, the ''King's Herd'' in Spanish) as early as the 16th century,<ref name="mini-wall-street" /> and is now considered the financial center of the island. A section of this district is often referred to as ''[[Milla de Oro]]'' (actually {{convert|0.47|mi|km|2|disp=or|sp=us}} long) due in part to the many banks and businesses located there.<ref name="mini-wall-street">{{cite web|url=http://www.puertorico-herald.org/issues/2004/vol8n47/PRSST0847-en.shtml|title=Eatin' Where The Cows Used To Roam: Hato Rey Dining At Its Best|author=Brenda A.

In the southern part of the city is the socially diversified community of [[Río Piedras]]. Founded in the mid-1850s, Río Piedras was a separate town which hosted sugar cane plantations and the estates of some of San Juan's wealthiest inhabitants (as well as their working-class staff). The Spanish colonial governors also had their summer home there on land which eventually gave way to the main campus of the [[University of Puerto Rico]]. In 1951 the municipalities of San Juan and Río Piedras were merged to redefine San Juan's current city limits. Today Río Piedras comprises the largest area of the municipality of San Juan.<ref>{{cite web|title=Official site of the University of Puerto Rico|url=http://www.uprrp.edu/|language=es|publisher=Universidad de Puerto Rico|year=2007|access-date=2007-05-06|archive-date=March 6, 2012|archive-url=https://web.archive.org/web/20120306033946/http://www.uprrp.edu/|url-status=live}}</ref> and is home to the "Plaza del Mercado" (Río Piedras [[Marketplace]]), the main campus and the Medical Sciences campus of the [[University of Puerto Rico]] and the [[San Juan Botanical Garden]].
