For Landmark East Harlem's Back to School Series feature, we are exploring the beautiful historic schools that have educated generations of East Harlem children. The schools highlighted in this tour were all built before 1950. Most of them were built in the first few decades of the 20th century, with the majority still in use today - some as schools, while others have been converted to community resource centers and housing. Sadly, some of these architectural gems have not survived the test of time and changes in development patterns.
