Origin and history
The castle of Lasalle, located in Siest in the Landes, is an ancient cellar emblematic of the ancient Viscounty of Orthe. Its origins date back to the 12th century, with the foundations of the hexagonal tower and the facade wall, testimonies of its medieval architecture. This site illustrates the evolution of defensive and agricultural constructions over several centuries, marked by major redevelopments in the seventeenth and eighteenth centuries, especially for the house and its dependencies.
The castle is distinguished by its spatial organization, preserved around two inner courtyards surrounded by operating buildings. These structures, typical of the Gascon caveries, reflect a dual vocation: seigneurial residence and agricultural economic centre. The hexagonal tower, the oldest element, and subsequent transformations (logis of the 17th century, 18th century arrangements) underline its adaptation to successive needs, while maintaining traces of its medieval past.
Ranked Historic Monument in 2012, Lasalle Castle includes in its protection all communes and operating buildings (cadastre B 47, 48). This recognition highlights its heritage importance, both as a vestige of local feudal history and as an example of evolutionary rural architecture. Its state of conservation and its spatial organization, considered a priori satisfactory (note 7/10), make it a remarkable site for the study of cellars in Gascony.
