Blaenavon Town began as a cluster of houses and other buildings near Blaenavon Ironworks and alongside their tramroad down the valley. Later the town centre grew up, sited on a few parcels of land which the company did not control. The whole surrounding landscape once controlled by the iron company is now a World Heritage Site. The whole of the town still reflects its origins in the iron industry and there is a surviving truck-shop on the south-east side of North Road Ironworks. On the ironworks site itself the conserved workers' housing of Stack Square survive on the south-east side.
Important sites within Blaenavon Town include: Blaenavon Ironworks, St Peter's School, St Peter's Church and the Worker's Institute.
