Casa Manuel Montt, National monument in Santiago commune, Chile.

Casa Manuel Montt is a two-story building at Merced 738 in Santiago, built between 1830 and 1840 in a neoclassical style that replaced the earlier colonial construction on the site. Only this two-story section survived the demolition of the 1980s; its ground floor now holds the Galería Merced 738, a commercial gallery.

Filiberto Montt and Luz Goyenechea built the house between 1830 and 1840, replacing an earlier colonial structure with a neoclassical design. Their daughter Rosario married her cousin Manuel Montt Torres in 1839, and the couple moved in after her parents' deaths. Manuel Montt was president of Chile from 1851 to 1861, and their son Pedro Montt Montt, president from 1906 to 1910, was born in the house. After the family sold it, it passed through several owners, including the Centro Republicano Español and the Caja de Empleados Públicos y Periodistas; it was declared a national monument in 1981 and largely demolished in the 1980s, leaving only the two-story section.

The house bears the name of a former Chilean president and reflects the shift from colonial to neoclassical design visible in 19th-century Santiago buildings. You can see this stylistic change in the facade details and the way the rooms are arranged inside.

The monument sits in central Santiago and is easy to reach via Merced Street. Access is available during gallery hours, making it convenient to visit while exploring the downtown area.

The house was demolished in the 1980s except for its two-storey section, which was kept and now holds the Galería Merced 738 on the ground floor. Before the sale, it had passed to owners including the Centro Republicano Español and the Caja de Empleados Públicos y Periodistas.
