Casa Mariquit is a heritage house in the Jaro district of Iloilo City, part of the extraordinary concentration of Spanish colonial and American-era mansions built by Iloilo's sugar oligarchy in the late 19th and early 20th centuries. The house sits close to the Lizares Mansion and the Lopez Heritage House, and the three together make a natural walking circuit of Jaro's elite residential history.
The building shows the characteristic features of Iloilo's colonial domestic architecture: a masonry ground floor, a wooden upper storey with large capiz-shell windows, and deep wraparound verandas designed to catch the breeze. Many of these Jaro mansions have been poorly maintained and are slowly deteriorating, which makes the surviving examples all the more worth seeing while they remain standing. The interior is not always open to visitors, but the facade and surrounding gardens are accessible and the streetscape of the surrounding blocks rewards a slow walk.
