Atop picturesque bluffs above the Ohio River, an outstanding collection of estates represents the work of landscape architects from 1875 to 1938. This textbook of landscape design of the "County Place Era" includes the works of the Olmsted firm, Carrere and Hastings, Bryant Fleming, Marian Coffin, and others. Today, a transportation study projects construction of a monumental bridge spanning the Ohio River which would split this 700-acre pastoral landscape. If the bridge is built, the continuity of this three-mile long collection of 21 contiguous estates would be lost forever.
