The Baldwin School (simply referred to as Baldwin School or Baldwin) is a private school for girls in Bryn Mawr, Pennsylvania, United States. It was founded in 1888 by Florence Baldwin. The school occupies a 19th-century resort hotel designed by Victorian architect Frank Furness, a landmark of the Philadelphia Main Line. The building was added to the National Register of Historic Places on April 27, 1979. Baldwin's brother school is the Haverford School, in nearby Haverford. History In 1888, Florence Baldwin founded "Miss Baldwin's School for Girls, Preparatory for Bryn Mawr College" in her mother's house at the corner of Montgomery and Morris Avenues in Bryn Mawr, Pennsylvania. The first class was composed of thirteen girls. The second Bryn Mawr Hotel was designed by Furness, Evans & Company and built in 1890–91. It is a five-story, "L" shaped stone-and-brick building in a Renaissance Revival / châteauesque style. It features a large semi-circular section at the main entrance, topped by a conical roof and finial. It has a steeply pitched red roof with a variety of dormers, chimneys, towers, finials, and skylights. In 1896, The Baldwin School began leasing the Bryn Mawr Hotel during the winter months for use as a dormitory for its boarding students. They leased it year-round beginning in 1912. In 1922, the school purchased the building and the surrounding for $240,000. Today the school has made many additions to "The Residence", as it is called, but has maintained the elegance of the original building. It is now used for the dining hall, many art studios, a black box, apartments for faculty and staff, music classes, and an Early Childhood Center. It also has many lounge areas for students and others. A two-story science building opened in 1961; it was enlarged in 1995 to accommodate the increasing number of students. The Upper and Middle Schools inhabit the three-story Schoolhouse, which was built in 1926. It was renovated in 1997. The Middle School on the third floor was renovated again in the summer of 2018. Grades 1-5 are housed in the Lower School building, which was completed in 1974. Changes have been made, for instance, painting the walls bright colors, to make it a warmer learning environment for the younger girls. Renovations completed in 2014 to "The Residence" specifically support the Pre-Kindergarten and Kindergarten classes. In 2015, a performing arts center was built called The Simpson Center, which can
