Sundials - World's Oldest Clocks

North American Sundial Society

A memorial, the Arc of Memory, will be completed in 2018 on the west side of the Garden of Provinces and Territories in Ottawa.  The design by Paul Raff's Sutdio is a "living calendar".  Raff described the memorial as a way to “honour the 8 million Canadians that can trace their origins to countries that suffered oppressive regimes of communism by creating an instrument of memory.”  In essence Raff is designing a huge digital sundial (or as he calls it, a "three dimensional calendar").   According to Erin Dommely of Azure Magazine,  the memorial is constructed of two curving walls 4 x 21 meters containing 4,000 short bronze rods arranged in 12 dense rows across a series of 365 stainless steel fins.  Erin describes the Arc of Memory's principle of having each rod uniquely angled towards the sun, whereby each hour of the day is illuminated each day of the year.

The two walls are split at the winter solstice and "On the darkest day of the year the design would invite visitors to step through in a metaphorical journey from darkness and oppression to lightness and liberty.”
