Many years ago the maze of pathways around the Portage Bridge were designed with a number of landings, lookouts, or other flats spots. I once heard that these were for sculptures.
Trivia fans may recall that at the time of construction, the proposed site for the new National Art Gallery was between Archives and the Supreme Court. The building would both face Wellington Street and spill down the cliff and have another face towards the river, in an area of prime waterfront that is still just another parking lot. So having a sculpture walk makes some sense.
It may be 30 years late, but some artwork has finally appeared. There is an exhibit called EcoArt installed on a number of the concrete walls. They are photographs, enlarged and printed on some transfer material, and bonded to the concrete walls.
The images were used last winter along the Rideau Canal; and will be displayed in the Portage area until October.
