The Vilvoorde prison, also known as 'De Korrektie', (the correction) is a well known spot in urban exploration. Visiting the location requires a bit of luck. The building is usually securely closed off, but every now and then a small opening appears, offering a glimpse into Belgium's penitentiary past.

The prison was built between 1776 and 1779 in a sober, classical style and housed approximately 270 prisoners. The commission, which was issued as a competition, came from the Austrian Empress Maria Theresa. The then-court architect, Benoit Dewez, was awarded the contract. He designed the new prison modeled on the 'modern' prison in Ghent. It was to be a building with the necessary emphasis on 'health' (hygiene and ventilation). However, Dewez was unable to realize the intended design and became the subject of sharp criticism and even accusations of fraud, which ultimately cost him his position as court architect.

The complex had a turbulent history, serving not only as a prison but also as a hospital and shelter for the homeless. For a more detailed history of the complex, please visit the Wikipedia page about the prison.
