Thiers wall
The station is named after the "Porte de la Chapelle", a gate in the nineteenth century Thiers wall of Paris, on the "Rue de la Chapelle", the old Roman road to Calais via Saint-Denis, now Route nationale 1. It was named after a village that was annexed by Paris in 1860 and was named after a chapel to Saint Genevieve built in the 6th century.
