Château de Chokier, Medieval fortress in Flémalle, Belgium.

Château de Chokier is a medieval fortress rising from a limestone rock above the Meuse valley. Its main building features a classical facade with two side wings that form an imposing structure commanding the landscape.

The fortress was founded in the 13th century by the Rulant de Fontaine family and withstood numerous attacks. It was partially destroyed in the late 14th century but continued to exist in its altered form.

The castle's name comes from the Surlet de Chokier family, who held the seigneury for two centuries from the late 14th century. Marie de Senzeilles, owner from 1564, wrote a will in blood in her prayer book leaving the castle to her nephew Paul de Berlo; after a long lawsuit, Rome ruled in his favour. The castle cannot be visited, but guided tours of the gardens are possible by appointment.

The rock face beneath the castle is a popular climbing site with routes for all skill levels. Climbers should bring proper equipment or arrange rentals, and should respect any local rules or access guidelines.

Marie de Senzeilles, twice widowed, married Jean-Jacques Barbiano de Belgioso in 1596; he had her locked away in Diest. Feeling death near, she wrote a will in blood in her prayer book leaving the castle to her nephew Paul de Berlo. Belgioso kept the castle anyway, and only after his death did Berlo win a long lawsuit, settled in Rome in his favour.
