Mansakenning
Why it's listed
Mansakenning is a 113-acre wooded estate off Ackert Hook Road in Rhinebeck, reached by a quarter-mile private drive lined with dry-laid stone walls. Its centerpiece is a stone manor house built about 1903 for Eugene Tillotson Lynch, with an unknown architect. The house has a Georgian-style hipped roof and five-bay front, but its irregular stonework, red-tinted mortar, diamond-paned windows and bracketed cornice give it a picturesque character. Inside, a parquet floor, coffered ceiling, turned staircase and classical mantelpieces survive. A guest cottage, barn, carriage house and sheds complete the grouping. The property is notable for its small scale and secluded setting carved out of the woods, which differ from the river-view estates and monumental houses of the period. Lynch descended from the Tillotson, Lynch and Livingston-connected families, so the estate also reflects the network of landed families in Rhinebeck. It illustrates the last phase of estate building in the town.
Significance in brief: The nomination argues the estate is a distinctive example of early twentieth-century country estate architecture in Rhinebeck. The manor house combines Georgian form with Picturesque stonework and Colonial Revival interiors, on a small scale in a secluded wooded setting. It was also built by an heir of the old Tillotson and Lynch families and illustrates the last phase of estate development in the town.
