Renfrew Benchmark

The term, "benchmark", has come to have many meanings. In this post we use the original meaning for it, "a surveyor's mark on a permanent object of predetermined position and elevation used as a reference point." These benchmarks exist in many places. The one pictured here occupies a place on the grounds of the Renfrew Town Hall on the northeast corner of Raglan Street South and Railway Avenue in Renfrew, Ontario.
