Niagara Square is a public square located at the intersections of Delaware Avenue, Court Street, Genesee Street, and Niagara Street in Buffalo, New York. It is the central hub of Joseph Ellicott’s original radial street pattern that he designed in 1804 for the then village of New Amsterdam. It continues to be the nexus of downtown Buffalo.
Its origins date back to the conclusion of the French and Indian War in 1763, which ended French domination of the Niagara Frontier and marked the advent of permanent settlement of the area. This trend increased after the Revolution, and in 1804 Joseph Ellicott (1760–1826) mapped a town on the banks of Lake Erie at the mouth of the Buffalo Creek. The site of the city was part of the vast land holdings of the Holland Land Company, a Dutch firm that had purchased most of western New York. Ellicott, who was the local Holland Land Company agent, had earlier in his career helped his brother Andrew survey Pierre L’Enfant’s plan for the new capital at Washington.
Within the center of the modern square is a large monument commemorating the assassination of President McKinley, who was assassinated in Buffalo during the Pan-American Exposition of 1901.
