The neo-classical three-storey building was constructed between 1846 and 1847 to designs by the Toronto architect William Thomas (and built by Garvie and Co.)[1] for the then Niagara District.
[2] The building replaced an earlier court house removed for fear of it being in-range of cannon fire from Fort Niagara.
Inside it had a courtroom, town hall chambers, offices and jail cells.
[3] The court-house function remained until judicial courts moved to St. Catharines in 1863; the building then served as town hall[1] and jail until 1866.
[2] As of the 2018 season, it was retired as an active performance venue and re-purposed for rehearsals, training, education, and expanded audience programs.
