Temple Beth El of Northern Westchester

Rehoboth is a historic former barn located on Aldridge Road in Chappaqua, New York, United States. It is a concrete structure that has been renovated into a house with some Gothic Revival decorative elements. In 1979 it was listed on the National Register of Historic Places.It was designed and built in the mid-19th century by newspaper editor and activist Horace Greeley as one of the agricultural experiments he dabbled in, testing whether concrete would make a good building material for farms. It was one of the first concrete structures in the country, and the first concrete barn. Greeley was so satisfied with the result he predicted that he would be remembered for it if nothing else.Two decades after Greeley's death, his daughter Gabrielle and her husband, the Rev. Frank Clendenin, pastor of a New York City Episcopal church, commissioned architect Ralph Adams Cram to remodel it into their house, which he named Rehoboth. They lived there for the rest of their lives, the remodeled house becoming one of the centers of Chappaqua's social life as the community completed its metamorphosis from country town to suburb. It has remained a private home since then.

The Greeley House is located at King (New York State Route 120) and Senter streets in downtown Chappaqua, New York, United States. It was built about 1820 and served as the home of newspaper editor and later presidential candidate Horace Greeley from 1864 to his death in 1872. In 1979 it was listed on the National Register of Historic Places along with several other properties nearby related to Greeley and his family.Built in the 1820s as a typical small farmhouse, it was expanded in the mid-19th century. Greeley, editor of the New-York Tribune, settled in Chappaqua shortly before the Civil War in the mid-19th century, living there with his family primarily during the summer. After a mob of citizens opposed to Greeley's abolitionist editorial stance threatened his wife at their earlier "House in the Woods," Greeley bought the farmhouse and moved his family there, near the hundred acres (40 ha) where he ran a small farm and practiced experimental agricultural techniques. After the war, Greeley built a mansion called "Hillside House" to live in, but died along with his wife shortly after the 1872 presidential election, where he ran on the Liberal Republican line against incumbent Ulysses S. Grant, so his children lived there instead, pioneering the suburban lifestyle that was later to define Chappaqua and its neighboring communities. Both of Greeley's other houses burned down later in the 19th century, leaving the Greeley House the only one extant.It, too, was almost demolished after falling into serious neglect in the early 20th century. After its restoration in 1940, it was used as a restaurant and gift shop. Following another restoration effort in the early 21st century, it is now the offices of the New Castle Historical Society.
