Plaza Sarmiento is located in a strategic location within the Rosario downtown area, and serves as a transport node for many urban and short-distance interurban bus lines. It occupies almost two blocks, defined by San Luis St., Entre Ríos St., Mendoza St. and Corrientes St. It is divided by San Juan St. (running east–west). It features a monument crowned by a statue of Sarmiento, known as a pioneer and promoter of public education in Argentina. The only route of the Rosario trolleybus system, line K, passes through Plaza Sarmiento.
The plaza currently hosts an outdoors artisans' fair several days each week.
