Info:
The Niagara District Court House was designated a national historic site of Canada in 1980 because, designed by the prominent Toronto architect, William Thomas, in the fashionable Neoclassical style, it is an excellent example of a mid-19th century multipurpose civic structure.
The Niagara District Court House marks a step in the transition to large and more sophisticated civic buildings after 1850. Its greater scale resulted from the inclusion of a wide range of functions. In addition to the courtroom, offices and jail, the Niagara District Court House also included a town hall and market. The structure was designed by William Thomas, an architect of national standing, adept at several classical styles. Source: historicplaces.ca\
