“ In the 17th century Clerkenwell became a fashionable place of residence. A prison erected here at this period gave place later to the House of Detention, notorious as the scene of a Fenian outrage in 1867, when it was sought to release certain prisoners by blowing up part of the building. Clerkenwell is a centre of the watch-making and jeweller’s industries, long established here; and the Northampton Polytechnic Institute, Northampton Square, a branch of the City Polytechnic, has a department devoted to instruction in these trades. ”
