Plaza Cruz, Public plaza in central Concepción, Chile

Plaza Cruz is a square in Concepción bounded by General Cruz, Joaquín Prieto, Salas and Angol streets. Its central perimeter is fenced and holds a fountain; the iron railing came from Plaza de la Independencia. On the Salas and Prieto sides there is a fenced multi-use court and a children's playground.

Plaza Cruz was laid out in 1876, making it the second-oldest square in Concepción after the Plaza de la Independencia. It was formally inaugurated on 13 October 1907 in a ceremony attended by numerous residents. The surrounding neighbourhood grew from railway workers' housing, since the station to Penco stood two blocks away and the road to Talcahuano ran nearby.

The square's name honours General José María de la Cruz Prieto, and a metal bust of him, 0.6 m tall on a pedestal reaching 2.4 m, stands on the grounds. The surrounding streets grew from railway workers' housing, since the Penco station stood two blocks away. Across General Cruz street, the María Inmaculada girls' school occupies a full block on the site of the old temple of the same name.

Multiple bus stops and parking areas are located around the square, making arrival straightforward. Nearby cafes and shops are open during the day to serve visitors.

The central perimeter is enclosed by an iron railing moved here from Plaza de la Independencia, installed in the 19th century to stop horses from drinking at the fountain. The railing now surrounds the plaza's own fountain, a detail most visitors pass without noticing.
