What is the particular hydraulic system of the château de Terraqueuse?

Two mills are powered by water from five captured springs through an original process unchanged since 1834. The lower mill uses the discharge water from the first mill to drive its three pairs of millstones. This ensemble produced electricity until 1960.

What buildings make up the protected ensemble?

Beyond the 17th-century château, the domain includes two historic mills, a chapel, a former orangery, an ice house, a vanished forge, a sawmill halted around 1950, farmyard buildings and various agricultural structures dating mostly from the 19th century.

Why was the site listed as a historic monument?

The entire domain, with its remarkable hydraulic facilities, 18th-century landscape design and coherent rural organization maintained for over 185 years, was recognized as protected heritage by decree on 17 October 1996.

Château de Terraqueuse de Calmont stands in Calmont (Haute-Garonne), in the Occitanie region of France.

The building is privately owned and no visits are on record.

Château de Terraqueuse de Calmont, built in the 17th century in Haute-Garonne, stands at the heart of an extensive rural estate organized around an exceptional hydraulic system. Two mills fed by five captured springs represent the site's engineering centerpiece, complemented by 18th-century landscape design: basins, canals and picturesque compositions. Since the 19th century, the domain has incorporated agricultural buildings that form an integral part of this listed historic monument.

What to know

The estate includes mills whose installation has remained unchanged since 1834, with a first mill converted to a residence in the late 19th century and a second one halted before 1925, preserving three pairs of millstones and historic equipment for electricity production until 1960.
The protected ensemble extends across several cadastral parcels and includes, besides the château and mills, important landscape features: large water bodies, canals, ponds, ice house, chapel, former orangery and agricultural buildings of the farmyard.
The original hydraulic system draws water through a process unmodified for over 185 years, with the lower mill recovering discharge waters from the upper mill.
