Turkey Point
As early as 1798, Lieutenant Governor Simcoe planned to fortify this point. By 1813 nothing had yet been done, and following Procter's retreat from Amherstburg the British decided to construct a navy yard and covering fort here. Difficulties in supplying the post, together with the unsuitability of the location led to abandonment of the project after only a blockhouse and part of a palisade had been built.
