Another prestigious all-boys private school, Columbus Academy, was founded in Bexley in 1911 and housed in a stately mansion in Bullitt Park. During the first half of the 20th century, Columbus Academy and Columbus School for Girls, both populated primarily by Protestant students from wealthy Anglo-Germanic families, held most of their joint school activities and "mixers" with each other. As Bexley became more diverse, sectarian lines like these were softened, such that now Bexley is known as somewhat progressive for a city of similar history and socio-economic background. (However, relations between CSG and St. Charles are still described as strained.) Columbus Academy grew, and relocated to Gahanna (northeast of Columbus) in 1968. It became co-ed in 1991.
