The Montauk Club is the oldest private club in New York City, still operating in an original building built expressly for it. The Venetian-inspired, stained glass-covered Park Slope beauty, which dates back to the 1890s is a testament to, and a physical embodiment of, the club’s tumultuous yet resilient past: at once historic, progressive, celebrity-studded, scandal-tinged, and obligatory stop for presidential candidates and still blooming today.
