From the Evening Record August 8, 1914:
The above is the perspective of the pavilion which the park committee proposes to erect in River Side park
at the foot of Bruce avenue, The structure will be unlike anything Windsor has ever erected. The
frame work will be entirely reinforced concrete, while the roof is supported by steel truss, and covered
with Spanish tile. The piers will be faced with brick. while the arches and frieze will be of stucco, inlaid
with tile, worked out in a harmonious color scheme. The first floor which will be constructed entirely
of concrete will form a delightful resting place on warm summer days, with a fine outlook over the
river. The basement confined to the east end of the building, will contain toilet rooms only. James C.
Pennington is the architect.
Above is the proposed location. I have never seen any photos or other references to this pavilion, it doesn’t appear in any records of Pennigton’s work, so I have to believe that it was never built. If I had to guess, I would suspect WWI played a big part in why it wasn’t built.
There is a long history in Windsor of unbuilt buildings.
