4. Rosemary Farm

The Roland Conklin estate, Rosemary Farm, in Lloyd Harbor had a slightly different fate than many of the previous entries. The mansion was destroyed by a fire in 1990, though several remnants still exist. Designed by Wilson Eyre in 1907 with Olmsted landscaping. Its owner, Roland Conklin was, among many things, one of the largest realty firms in Kansas City, a business that moved to New York City in 1893, prompting the building of this estate.

Conklin abandoned his estate in 1924 when his wife died. The remaining bits of the estate include the clock tower from the old carriage house, along with the now-restored ampitheater, cleaned by the Huntington Historical Society in 1986, and can be entered using a stone bridge.
