Halifax, Nova Scotia

Bayer's Lake Mystery Walls

No one knows the origins of the mysterious stone ruins discovered on a hillside in Halifax. 

On a hill overlooking Bayer’s Lake Business Park in Halifax, Nova Scotia, there are the remains of a five-sided stone building, a long stone wall, and a stone staircase, and no one knows why or when they were built.

Constructed with flat-surfaced ironstone slate rocks, the Bayer’s Lake Mystery Walls have been protected under Nova Scotia’s Special Places Act since 1991, after they were discovered during development of the area. Various archaeological groups have since studied the structures, but the artifacts uncovered have been deemed too young to offer clues about their origins.

The area is accounted for in documents following the sale of the land through the years, but none exist to account for the structures. While some believe they predate Canada, most believe they served some kind of military function during the early settlement of Halifax in the late 1700s and early 1800s.

They may have been used in 1758 to prepare for the storming of the Fortress of Louisbourg, or for defense during the war of 1812. Its elevated position on a hill, with a wide view of the surrounding area, suggest these kinds of answers to the mystery, as does the fact that when Halifax was founded, in 1749, it was used as a military garrison town.

In the summer of 2016, the Nova Scotia Archaeology Society was given a grant to rent an x-ray fluorescence system for analyzing the soil chemistry around the walls and fort in 2017. This will be minimally invasive, since the x-rays can be used to analyze the soil without much digging, and the whole process will take only two days. Which means that, within a year or two, the Bayer’s Lake Mystery Walls may become, simply, the Bayer’s Lake Walls.

Know Before You Go

The stone ruins are monitored by trail cameras since they have been vandalized and parts of the structures removed without permission in recent years. Walking on the walls is forbidden because it can cause them to collapse.
