Hacienda El Huique, Cultural heritage site in Palmilla, Chile.

Hacienda El Huique is a rural estate in Palmilla, Chile, whose houses grew gradually around fourteen courtyards with corridors. The residential courtyard, serving as the entrance, has a formal French garden and century-old palms. Walls are adobe on brick foundations, with oak, cypress and espino timber, clay tile roofs and clay tile floors where the original cobblestone no longer survives.

The estate originated from Larmagüe land grants in 1613 and passed to the Echenique family in 1751, who expanded the grounds and built new structures. It later became a national monument under Chilean Army conservation management beginning in 1976.

The neoclassical church built in 1852 displays a three-arch portico with a wooden tower rising about 23 meters, representing rural Chilean architectural traditions. This structure shapes the visual identity of the entire estate.

The property is open to the public through guided tours to an on-site museum that provides an overview of the estate's history and layout. Comfortable shoes are recommended, as the grounds are expansive and exploring the various courtyards involves walking.

Gertrudis Echeñique inherited El Huique individually and continued her father Juan José Echenique y Bascuñán's building work; with her husband, President Federico Errázuriz Echaurren (1896–1901), she added rooms and improved furnishings. Their daughter Elena, also sole heir, did the same.
