Halifax is home to many famous military sites dating back to the early 1800's as the Halifax Harbour was and continues to be an important naval port of call.  Halifax was ideal for a military base, with the vast Halifax Harbour, among the largest natural harbours in the world, which could be well protected with artillery battery at McNab's Island, the Northwest Arm, Point Pleasant, George's Island and York Redoubt.

In its early years, Citadel Hill was used as a command and observation post, before changes in artillery that could range out into the harbour.

This week Adam takes us on a historical walk through the York Redoubt, which was one of the sites used to protect the Halifax Harbour from enemies.
