The Raleigh factory was situated in Hanover Quay Dublin. From Thom’s Dublin Street directory, Raleigh was first listed at No 6 Hanover Quay in 1939. In 1943, they moved to Nos 8-11. A full range of Raleigh Cycles was manufactured at this Dublin factory in the post war era. Being an early factory, built and used before safety regulations came into practice, the wooden floor soaked up all the oil, grease and other flammable lubricants over the years, so that when a fire started in 1976, the whole factory burned to the ground. This lead to the biggest insurance payout in Irish history, although this has probably been surpassed by now! Unfortunately all the records stored in the factory were lost at this time.

After the fire, Raleigh stayed in Ireland, but only as a distributor, not a cycle manufacturer. They built another factory, but quickly downscaled to suit their distribution network.

In 1939 Raleigh opened a bicycle factory at 6 Hanover Quay, Dublin, Ireland and commenced bicycle production there. The Raleigh (Ireland) business expanded and moved to 8–11 Hanover Quay, Dublin in 1943. The plant produced complete bicycles and Sturmey-Archer hubs, and remained in production until 1976, when the factory burned down. Models produced there latterly were the Chopper and Triumph 20. The head badges changed in the late 1960s, possibly after the passing of the Trade Descriptions Act in the UK. Dublin-made machines no longer had "Nottingham England" on the Heron or Triumph head badge, the panel being left blank instead.
