Convento de San Francisco, Franciscan friary and national monument in Corrientes, Argentina.

Convento de San Francisco is a friary and national monument in Corrientes featuring thick adobe walls about 1 meter (3 feet) in diameter and wooden columns. The neoclassical facade contrasts with a baroque interior design, where a pipe organ also stands.

Construction of this friary began in 1589 under Friar Luis de Molina and was completed in 1607. The chapel underwent rebuilding work between 1861 and 1867.

The friary is dedicated to San Francisco Solano, and its interior preserves a semicircular atrium, a pipe organ and a pulpit laminated in gold. From here, missionary initiatives left to found the reductions of Itatí in 1615 and Santa Ana de los Guácaras in 1621.

The friary occupies the block bounded by Mendoza, Plácido Martínez and Fray José de la Quintana streets, in the founding centre of Corrientes. The entrance is on Mendoza at number 420. Inside, look up at the colonial roof structure: muslera tiles laid on a lattice of tacuaras canes tied with rawhide strips, resting on palm posts.

The friary's colonial roof tiles rest on a lattice of tacuaras reeds tied with rawhide, and the original hand-carved doors and palm-wood posts are still in place. The walls are adobe about one metre thick, held by hardwood columns.
