The Eccleston Street building known as ‘Flat Iron House’ (owing to its unusual shape) is the former Lancashire Watch Company Warehouse. Prescot was once famous for watch-making. In 1795, it was said that ‘the town produces the best in the world’. At one time, there was a workshop at the back of every house in Eccleston Street and nearby Atherton Street, where parts were made or watches assembled. The watch trade eventually died out in Prescot in the 1920s.
