Small Arches Everywhere!

Written by Pete Ryder

St. Lawrence Market in Toronto has been a bustling site of commerce since the early 1800’s. In 1851 the market was expanded. That is probably the timeframe of the pictured sewer system. The lakeshore is about 1500 feet today. While the shoreline was likely closer in 1850, the outflow tunnel is quite a structure in any case!
The center tunnel appears to be 4 feet tall and 3 feet wide. Side tunnels radiate out periodically so as to provide drainage for the entire open-air marketplace that stood here. I spent the previous two weeks building an 8-foot arched foot bridge of Ontario limestone and was feeling quite accomplished, until I saw this!
