Oud Gerechtsgebouw, Protected courthouse in Hasselt, Belgium.

Oud Gerechtsgebouw is a protected courthouse occupying a corner site at Havermarkt and Cellebroedersstraat in Hasselt, decorated with stone sculptures by Jan Boedts. The building comprises multiple stories with detailed architectural elements that reflect its former judicial importance.

A Cellebroeders monastery stood here from the 15th century and served as prison and court after 1790. Retreating German troops set the building on fire on 11 November 1918. After a 1923 design competition, Brussels architect Jerôme Vermeersch's scheme was built on the same spot, completed in 1936 after financial delays.

The building's name reflects the Cellebroeders, a monastic community whose presence shaped the area for centuries. Its sculptured stone facade conveys how this location embodied authority and the justice system for generations.

The building stands at the corner of Havermarkt and Cellebroedersstraat, about 50 metres southwest of the Grote Markt. Judicial services left in May 2012, and redevelopment began in autumn 2018. The interior is not a public courthouse; check current use before planning a visit.

The building was sold in March 2017 to developer Kolmont - Tans Group for redevelopment. In May 2018, while standing empty, it was opened as a study space for students, and renovation work began that autumn.
