Casa Colorada, Colonial house in Santiago, Chile

Casa Colorada is a two-storey colonial house at Merced 890, near the Plaza de Armas. Its red upper facade carries two round white-framed windows and a curved white gable above the doorway, while the grey stone base holds a carved portal with two pilasters and tall panelled wooden doors. A plaque on the stone reads "MUSEO DE SANTIAGO".

Mateo de Toro Zambrano commissioned the house from Portuguese architect Joseph de la Vega in 1769; it was finished in 1779 and was the first residence in Chile with a two-storey facade. After independence the Irarrázaval family owned it until 1924. A 1963 fire in a print shop in the attic injured 13 people, and the 2010 earthquake damaged the oak beams and stone mortar, closing the museum until its reopening on 31 August 2024.

The house is known as Casa Colorada for its deep-red walls. Since 1981 it has held the Museo de Santiago, which occupies five rooms and traces the city from the first settlements of the Mapocho Valley to the early 21st century. Visitors pass through two large patios to reach the galleries.

The Museo de Santiago reopened on 31 August 2024 after rehabilitation work that began in 2020, receiving its first visitors on 3 September. The building stands at Merced 890, facing the Paseo Phillips, a short walk from the Plaza de Armas. The museum occupies five rooms reached through two large patios.

The structure uses sillar stone walls, oak roof framing, and canelo wood elements, making it a rare example of colonial residential building techniques. This material choice reflects what was available locally and imported to Chile during that period.
