Quebec Martello Tower 4

 (1808-1871) - A British colonial Martello Tower established by Ralph Bruyeres in 1808 on the Plains of Abraham in present day Quebec City, Quebec, Canada. Abandoned in 1871 as the British military left Canada.

History
Martello Tower 4 was much the same as Martello Tower 1 and could also garrison 12 men. It was apparently home to a peace officer and his family from 1892 to 1907.

Current Status
