100 East End Avenue in Manhattan, New York City, is the longstanding home of The Chapin School, an all-girls independent day school established in 1901 by Maria Bowen Chapin. Originally opened as "Miss Chapin's School for Girls and Kindergarten for Boys and Girls" at 12 West 47th Street, the school moved several times during its early years, relocating to East 58th Street in 1905 and then East 57th Street in 1910. In 1928, Chapin School settled into its current building at 100 East End Avenue, overlooking the East River.
The building has served as the unified home for all of Chapin’s programs, reflecting founder Maria Bowen Chapin's vision that students be educated "under one roof." Since 1928, the structure has undergone multiple expansions and renovations approximately every decade, growing vertically and horizontally while maintaining architectural harmony. Notable expansions include the addition of the Ethel Grey Stringfellow Wing, the Annenberg Center, new floors, and extensive modernization efforts completed in the 21st century.
The school has a rich history of educational innovation and leadership. Maria Bowen Chapin was an early feminist and educator who emphasized rigorous academics, character development, and physical education at a time when such approaches were uncommon. Under successive headmistresses, such as Mary Cecelia Fairfax and Ethel Grey Stringfellow, the school enhanced its curriculum with increased focus on science, health, and cultural engagement, shaping Chapin into a model private school on the Upper East Side.
The building houses extensive facilities including multiple science laboratories, art studios, music and computer labs, a two-story library, multiple gymnasiums, a greenhouse, and a black box theater. Recent expansions have added a rooftop turf practice field, fitness center, and a regulation-size gymnasium on the top floor, ensuring that the school’s physical plant supports a comprehensive K–12 education all within a single urban campus.
Throughout its nearly century-long presence at 100 East End Avenue, Chapin School has grown in size and reputation while remaining deeply rooted in its founder’s ideals, making the building a landmark of educational history on Manhattan’s Upper East Side.
