The Concord Resort Hotel (pronounced KAHN-cord) was a resort in the Borscht Belt part of the Catskills, known for its large resort industry in the 1950s, '60s, and '70s. Located in Kiamesha Lake, New York, the Concord was the largest resort in the region until its closing in 1998. There were over 1,500 guest rooms and a dining room that sat 3,000; the resort encompassed some 2,000 acres (8.1 km2). Although the resort was a kosher establishment, catering primarily to Jewish vacationers from the New York City area, it was more lavish in decor and activities than comparable large Catskill resorts.
A small establishment near Kiamesha Lake called the Ideal House existed during the 1920s and 1930s. Arthur Winarick acquired the property after a default and rebuilt it in 1937 as the 500-bed Concord Plaza. Keeping up with Grossinger's following World War II, the then-renamed New Concord Hotel rapidly expanded and added amenities to match Grossinger's ski slope and golf course. The Tropical Indoor Pool opened in 1951, accelerating the race. Expansion continued in the 1950s, when prominent hotel architect Morris Lapidus was hired to design new modern style guest wings. At the Concord Lapidus worked with architect-interior designer Theordor Muller on interiors for lobbies, dining spaces and night clubs. A rotunda and promenade, as well as the huge Cordillion Room, Night Owl Lounge and the even bigger Imperial Room night club were added. Lapidus employed his signature floating stair design in the rotunda to give guests an opportunity to make a grand entrance.
The Concord was known for its impressive entertainment venues. The original Cordillion Room opened in the 1950s with 1500 seats, along with the Constellation Room with its distinctive undulating bar. Winarick felt that more was needed and the Lapidus-designed Imperial Room seated 3000 in a nearly circular space, perhaps the largest in the Catskills, and a popular venue for major entertainers.
Guest quarters in the tower sections were regarded as somewhat impersonal. Up to ten story guest wings replaced the original hotel in the 1950s. A Lapidus-designed 1959 wing featured 210 rooms with projecting bay windows and his-and-her bathrooms, each with a dressing area.
