The MacNab Street Presbyterian Church was established as a congregation in 1854 during a cholera epidemic. The current building’s construction began in 1856, with funding provided in large measure by two families — Dr. Calvin McQuesten (of Whitehern) and the Honourable Isaac Buchanan (of Auchmar Estate). Scottish stonemasons constructed the main building, using locally quarried stone. Over the next 25 years, two additional buildings were added to the site: a manse and a school. Following the First World War, an addition was made and then, in 1935, the interior was completely renovated and a nine-window stained-glass installation by the Scottish artists William Wilson and James Ballantyne was commissioned. The building was praised for its “the simplicity and good proportion of its exterior design.” Today, it is part of the MacNab-Charles Heritage Conservation District.
