CONCORD LIGHTHOUSE AT HAVRE DE GRACE, MARYLAND

Maryland's oldest continually operated lighthouse.  Built in 1826 the light house saw the birth and death of the famed Susquehanna flats waterfowl market hunting days.  John O' Neill was the original lighthouse keeper and used the small canon to defend the area from the British in the war of 1812.
