A walking tour of 100 historic mansions in Montreal's Golden Square Mile, with background about each and additional info about local architects and styles. The basic tour begins at McGill gates and takes under two hours.

Montreal will always seem different after you learn to recognize the Square Mile mansions.

The app can be used as a general guide to the mansions if you choose not to follow the basic walking route.

All the sites are mapped and photographed and have a description. Clicking an icon causes a page about the nearest notable building to automatically open.

Assembling the site descriptions required considerable research. As a result the app includes information not readily available elsewhere.
