As the first 'firm ground' to the East of the marshy MossLake that was to become Abercromby Square, it was also used as an informal marker for the edge of the town boundaries ( which technically ended somewhere near the Moss-Lake brook a few dozen yards to the West).
It was reached from Hope Street via a footpath and wooden bridge leading from just next to the current Philharmonic Hall, and crossing where Abercromby Square gardens are now.
