Russ and I have been pondering this for quite a while.
From approx 1797 to 1801, there was a communication line constructed as a semaphore telegraph system from Halifax, to Windsor, down to Annapolis Royal. It has also been referred to as an ‘optical telegraph’ and ‘visual telegraph’ line.

The Prince planned to extend the line to Fredericton (and likely Quebec) possibly even to Fredericton. There seems to be some doubt that the line made into the NB wilderness, but historic sites counter this premise:
For a system that was revolutionary (based upon a European French design), there really isn’t much that has been written about it. It seems likely, based on a 7 to 12 mile separation of towers along the line, that there could have been approximately 20 platforms built. Question is – where were they? There are guesses, but no primary reference descriptions.
It is probable that there was a tower built at Windsor (Fort Hill). It seems that quite a few of the tower locations on the Halifax peninsula are fairly well known, but once the line headed into the wilderness, it was lost to memory.
It would be fascinating finding old paths/roads and tower locations and take a look around. Even though only manned for 2-3 years before the prince left the province, I’m sure there would be fascinating artifacts and stories at these sites…
