The Sharp Street Ragged School was actually founded in 1853 but this buildng was built in 1869.  Clare Hartwell in the Pevsner Guide to Manchester says that "it is said to retain a little-altered interior with ground-floor partitions which divided the reception class of wild street children from those who have been subdued."

The map below shows a school on this site but the map was drawn between 1844 and 1847 at least 6 years before the Sharp Street Ragged School was founded and at least 21 before the building above was built.  The school on the map is called the Angel Meadow School.
