Fort Leopold was an important part of the defense belt around Diest in the nineteenth century. It is located on the Lazarijberg and offers a beautiful view of the city as well as the citadel located a little further away. The intention was for the fort to protect the city, but a few years after it was put into use, it was already converted into a prison. Punished soldiers from the Leuven prison were brought to the fort. Writings on the wall are still silent witnesses of that time. Prisoners were also locked up during the world wars. The fort was used by the paratroopers in the second half of the twentieth century, but they moved out more than 20 years ago. Since then, only a caretaker has been maintaining the building. In 1996 it became a protected monument. The building is made of hundreds of thousands of bricks and has very thick walls, making it very cold and dark, the ideal habitat for bats according to the Agency for Nature and Forest, which is the current owner.

Over the years, the castle was modernized and updated. This included the tower, whose heavy line of the fortified wall was broken by irregular window and door arrangements. The castle still houses remarkable works of art. The neo-Gothic armory houses a cast-iron stove from 1539 and two marble Renaissance mantelpieces. The castle also contains important paintings, tapestries, gold leather wallpaper, and furniture in a variety of styles. (Municipality of Westerlo)

An old fort that dates from the war. If there is a guide you can visit it. Really worth it. When you are on top of the fort you have a view over the entire city of Diest. In the fort also live a lot of bats.

Today, it's undergoing transformation into a new city district, serving as a cultural and recreational hub while preserving its military past.
