Frontenac County Courthouse, Kingston

The Frontenac County Courthouse is a distinguished example of Neoclassical architecture designed by Edward Horsey. The building, which opened in 1858, is constructed from limestone and prominently features the Royal coat of arms of the United Kingdom on its front facade. Overlooking City Park and the scenic expanse of Lake Ontario to its south, the courthouse is a significant landmark in the city’s historic landscape.

The Classical Revival style of the courthouse was influenced by George Browne's Neoclassical Kingston City Hall (1842-1844), featuring a three-storey central block with symmetrical two-storey wings ending in pedimented pavilions. In 1874, a major fire necessitated alterations to the original design, which were carried out by architect John Power. One of the most notable additions from this reconstruction is the domed roof tower, which enhances the building’s classical aesthetic and provides a striking focal point.

Above the dome, a lantern with six semi-circular arches and attached columns mirrors the details below, topped with a flagpole. Additionally, cupolas with octagonal drums and ribbed domes were added to the end pavilions during the reconstruction. The courthouse's design also thoughtfully incorporates larger second-storey windows, which provide ample light to the spacious courtroom areas on the original second floor.

Further enhancing its historic charm, a three-tiered fountain was added to the courthouse grounds in 1903. This addition, along with the existing architectural elements, contributes to the courthouse's status as a cherished heritage site. In recognition of its architectural and historical significance, the Frontenac County Courthouse was designated a National Historic Site of Canada in 1980.
