The Town Mission Ragged School in Brook Street in Nottingham was built in 1858. Ragged schools were developed from an idea of John Pounds, a Portsmouth shoemaker, who believed that poor children should have basic schooling rather than being sent out to work. The Earl of Shaftesbury then formed the Ragged School Union in 1844.
Designed by C. H. Edwards it was officially opened by the Earl of Shaftesbury in 1859.
Now the building is the headquarters of the Nottinghamshire Wildlife Trust. You can find some more photos here.
