Built in 1825, this neoclassical, loyalist style building expanded several times. Its orange roof and unique  have coupola become the focal point of L'Orignal, now apart of the Township of Champlain.


In 1998, Ontario's oldest prison closed its doors. It was also the only francophone jail in Ontario. However, the second floor is still occupied by the oldest courthouse in Ontario. To this day, the courthouse is still in function.  


Open to the public since 2007, this historical site now under the Ontario Heritage Act invites you to soak in the atmosphere of what used to be prison life in L’Orignal.

In 1823, discussions were held in order to build a court and a prison at L’Orignal for the Ottawa District. Jacob Marston, a prominent local citizen, offered two acres of land to erect such a building. In 1825, a beautiful stone construction designed in the Neo-Loyalist style was inaugurated. This building was added to a number times, one being the West wing in 1850 and another the East wing in 1862. The administrative offices of the United Counties of Prescott-Russell were added in 1962. Even though the oldest prison in Ontario was decommissioned in 1998, the second story was taken over by the Court. Topped by a distinctive orange roof and a remarkable dome or cupola, this unique building remains the most significant in L’Orignal, which is now part of the Township of Champlain.

The importance of this heritage building reaches far beyond the territory of the United Counties of Prescott-Russell. Indeed, this is the oldest judiciary building still in operation in Ontario and one of the few existing buildings used as government offices before the enactment of the Municipal Act of 1849. This building stands as a witness to every step in the development of the regional government and in the evolution of the judiciary system in Ontario since 1825, thus spanning nearly two centuries

In addition to being the oldest building in the United Counties, this complex remains one of the most significant in Ontario, particularly for the Franco-Ontarian Community. When this institution was closed, it was the only Francophone correctional centre in Ontario. L’Orignal Prison was recognized for the excellence of the educational, spiritual and health programs and services it offered in French. In short, this place is a testament to a strong Francophone presence in Ontario
