Although primarily a residential area, the commune of San Giorgio a Cremano has maintained a local textiles industry since the Middle Ages, possibly as early as the 8th century. Threatened in recent times by cheap imported textiles from Asia, the local industry has managed to survive through the local economic support that can be found amongst Italian communities. Hand-weaving and industrial textile industries are both still found in the commune, and shirts and ties of a high quality which are exported internationally are manufactured there.
