POLO PARK SUNDIAL
If you live in Manitoba or have visited Winnipeg you will likely know that Polo Park is a large mall located on the strip, Portage Avenue.

At one time, many years ago, there was a rather large sundial which stood outside the entrance of the mall. This sundial was removed in the '60's when the mall underwent major renovations. Nobody seems to know where it went but as it was constructed of concrete it is likely to have been demolished.

However, here are a couple of photographs of the sundial courtesy of John Walker from Pinawa.

This sundial is an example of an equatorial dial. It is the simplest form of dial and is the one used to layout the hour lines of most other dials when the graphical method of sundial design is used.

Polo Park Sundial Hour Lines This close up shows the layout of the hour lines. They are equally spaced apart at 15 degrees. The gnomon, in this case the large concrete pillar is set to point at the North Celestial Pole. It is placed so the angle between the top surface of the gnomon and the horizontal plane of the ground is equal to the latitude of the place where the sundial is positioned. In this case it is Winnipeg.

This dial will indicate the local time from sunrise to sunset.
