Cedarmere-Clayton Estates, Historic district in Roslyn Harbor, US.
Cedarmere-Clayton Estates are two historic properties built in the Colonial Revival style, set along Bryant Avenue in Roslyn Harbor, New York. Each property includes a main house surrounded by gardens, ponds, and outbuildings that formed the original residential compounds.
The writer William Cullen Bryant purchased Cedarmere in 1843 and reshaped an older house that was already on the land. Clayton was added later by another family and shows how tastes in residential design shifted over the following decades.
The two estates sit along Bryant Avenue and show how wealthy families on Long Island's North Shore once arranged their private grounds, with gardens, ponds, and outbuildings still in place. Clayton now functions as an art museum, while Cedarmere keeps its period furnishings and gives a sense of daily domestic life in that era.
Nassau County Parks manages both properties and offers guided tours and programs throughout the year, so it is worth checking what is available before visiting. Both sites are open to the public, and visiting one does not automatically include the other, so plan accordingly.
A small building from 1862 on the Cedarmere grounds has the initials WCB worked into its main window in the Gothic Revival style. It was originally built to draw water from a spring and supply the estate, a function most visitors do not expect from such an ornate structure.
