Conjunto Urbano Plaza 25 de Mayo, National historical monument at Plaza 25 de Mayo, Corrientes, Argentina

Conjunto Urbano Plaza 25 de Mayo is an urban complex in Corrientes with architecture spanning the 1800s and 1900s. The ensemble features covered galleries, projecting balconies, and interior courtyards that are typical of riverside colonial towns.

The plaza began as a colonial Arms Square in the colonial period and evolved into a center for trade and communication. Government House was constructed between 1881 and 1886, establishing the built form that defines the space today.

The name of the complex recalls 25 May 1810, when the first patriotic government was installed in Buenos Aires. The church and convent of La Merced, dating from 1728, keep 18th-century confessionals carved in cedar by indigenous craftsmen. The former Bedoya house, built in 1924, has housed the Rectorate of the Universidad Nacional del Nordeste since 1957.

The complex sits in downtown Corrientes and houses multiple government buildings, educational institutions, and a Regional Crafts Museum. The museum occupies a colonial house from 1806 and provides insight into local artisan traditions.

The 1728 church of La Merced on Calle 25 de Mayo keeps 18th-century cedar confessionals carved by indigenous craftsmen, a detail easily missed from the square outside.
