Cowan House

Cowan House, built circa 1858, is a Georgian-style dwelling with Italianate features, including the bracketed eaves and portico elements. It was home to businessman and mayor W.F. Cowan and his family. Today, it serves as offices and meeting rooms for St. George's Memorial Church. Tours of the main floor reveal many original details of this heritage home.
