Origin and history
The Terraqueuse estate, located in Calmont (Haute-Garonne), originated in the acquisition of the Baronie de Calmont and Terraqueuse in 1641, when mills were already attested to there. These hydraulic installations, powered by an original five-source capture system, form the technical core of the field. The site still retains today two mills whose layout has not evolved since 1834: one, transformed into a dwelling at the end of the 19th century, uses a brick ovoid basin; The other, which was stopped before 1925, housed three pairs of grinding wheels under a vault and electrical equipment until 1960. A sawmill, backed by this mill, ceased its activity around 1950.
In the 18th century, the estate was built in a romantic landscaped style, with basins, canals and artificial ruins, reflecting the aesthetic tastes of the era. The agricultural outbuildings, built or renovated in the 19th century, complement this coherent rural complex, including a cooler, a bassyard, a washhouse, and an old orangery chapel. The hydraulic system, remarkable for its complexity, illustrates a rare technical mastery, combining water retention, leak channels and forced pipes to operate the mills and generate energy.
Ranked a Historical Monument by order of 17 October 1996, the Terraqueuse estate protects not only buildings (castle, mills, outbuildings) but also hydraulics and historical soils, such as moats, ponds, and old vegetable gardens. However, the accuracy of its location remains poor (level 5/10), and the site, owned by a private company, retains some of its mysteries, as the exact origin of its first developments in the 17th century, only supposed.
