Niagara County’s geographic position is the reason for its geo-political prominence as an Outpost of Empires and as stage for stories that are a significant part of American history. The international Niagara River borders Canada and Western part of the county while Lake Ontario is the northern boundry. Tonawanda Creek is the Southern boundry thus suggesting a peninsula feature.
