Origin and history

The domaine de la Palanque, located in Saint-Louis-de-Montferrand (Gironde), is a former noble house dating mainly from the 18th century, with renovations in the 19th century. The main house, made of cut stone, adopts a plan in L with a two-storey square pavilion. Its facades, decorated with Louis XVI bosses and balustrades, mask croup roofs. A terrace in blacksmithy and a pier on the Garonne remind of its historic link with the river. Originally called Grand Allure or Grand Allune on 17th century maps, the estate was organized around a body of square houses flanked by pavilions, one of which dominated the river.

The outbuildings, scattered on the boundary of the park, include a large long-walled building, an entrance house near the stone gate, and an artesian well. The half-moon gate, with grids and batteries decorated with volutes, marks the entrance to the estate. Inside, the vestibule distributes rooms to the 18th-century panels and marble fireplaces, while elements Napoleon III (like a square tower) testify to the 19th-century transformations. The map of Belleyme (1762-1783) and the cadastre of 1824 reveal its evolution: from a compact agricultural complex to a more dispersed domain, with partial destruction of the original buildings.

Partially classified as historical monuments since 1966 (façades and roofs), the estate retains remains of its dock on the Garonne, highlighting its past role in river exchanges. A lintel dated 1770, 18th-century panellings and chimneys are associated with later additions, such as orangery or the monumental gate. The site, now surrounded by cultivated land, illustrates the adaptation of a noble home to agricultural and residential needs, from the Enlightenment to the Industrial Age.
