Heritage Open Day: Mossley was built on the wool and cotton industry and the architecture of the houses reflect the needs of the industry (and its workers) as well as teaching about social changes and heritage . Mossley's Mill Heritage can be appreciated by observation of both its landscape and its buildings. Famous Mill Owners built houses for their workers, their managers and their families - the difference in style and structure can be seen whilst walking along most Mossley streets. There are important buildings which reflect the changing social needs of the community. The history of some of these buildings and houses will be displayed, visitors will also be able to access a self-guided trail around some of them and will be directed to an online source to access video/photos and audio of Mossley's heritage.
