The Classicist main building of the Õisu Manor was built at the turn of the 18th and 19th centuries. The wide and high parade staircase with sculptures of white marble makes the mansion impressive; one of the sculptures is a Protege of Home, the other one symbolizes Power. Many outbuildings belong to the Manor Ensemble, of which one of the most interesting one is the so-called "wry stable". There is an English-style park, one of the first in Estonia, behind the main building.
There has been a Õisu dairy school since 1922. At present school provides training in dairy work and other branches of food processing.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
