This property was once part of the Concord Hotel, the largest Borscht Belt hotel, with 1,200 guest rooms, a football-field-sized dining room, a 3,000-seat theater called the Imperial Room, a "Monster" golf course, and many luxurious amenities overlooking Kiamesha Lake. It hosted performers including Judy Garland, Tony Bennett, Barbra Streisand, Jerry Seinfeld, Joan Rivers, Diana Ross, and Aretha Franklin, and in 1968 Martin Luther King Jr. delivered the keynote speech at the Rabbinical Assembly convention there ten days before he was assassinated. The Concord closed in 1998. This property was also once part of Breezy Corners Bungalow Colony, which had its own nightclub, the Revolution Room, where major 1960s and 1970s music acts including Jethro Tull and Fleetwood Mac performed, before Breezy Corners closed in 2008. Along with about 20 hotels and bungalow colonies, other notable Kiamesha destinations included the Gibber, the Gradus, and Mayfair Hotels. From the 1920s through the early 1970s, the Borscht Belt was the preeminent summer resort destination for hundreds of thousands of predominantly East Coast American Jews. Exclusion from existing establishments in the 1920s drove Jewish entrepreneurs to create more than 500 resorts, 50,000 bungalows, and 1,000 rooming houses in Sullivan County and parts of Ulster County. The Borscht Belt provided a sense of community for working and vacationing Jews and strongly influenced American culture, especially entertainment, music, and sports. Some of the most well-known and influential people of the 20th century worked and vacationed there. Beginning around 1960, the Borscht Belt began a gradual decline due to factors including the growth of suburbia, inexpensive airfare, and generational changes.
