The city of Kingston, Ontario was a military outpost for many years. The War of 1812, between America and Britain (Upper Canada), caused to be built many fortifications. Among them Fort Henry and supporting structures such as several Martello Towers which still stand today, beautifully preserved.
I had the opportunity this summer to tour one of these amazing structures, which at one time held about 20 soldiers to be on watch for, and repel, any attacks from America over Lake Ontario and the adjoining shoreline. The tower also contains a 35 pound cannon which rotates 360 degrees.
I was particularly taken with the amazing stonework and especially this winding staircase which come down from the upper cannon level to the main floor. I like the way the light shines up the stairs and reflects off the stonework.
