## Courthouse

William Buell granted the land for construction of the Brockville Courthouse atop a hill rising from the Saint Lawrence River. A broad boulevard extends to the main street. One of the oldest courthouses in Ontario, it was erected in 1842. The original plan had been to build one in Johnstown Township, but the land there was too swampy. Instead, it was built in Elizabethtown Township.
The figure of Themis, a blindfolded woman holding the scales of justice, was made by master carver William Holmes in 1844. This statue was named "Sally Grant" by Paul Glasford, the chair of the building committee, in honour of the woman who posed as the model. It was erected in 1845, damaged by Hurricane Hazel in 1954 and rotting by 1956. The original is on display at a Westport museum. A replica carved by Robert Kerr of Smiths Falls was placed atop the courthouse in 1982.
