View of the southern end of the site following the land clearance taken from the towpath of the Hafod Works. Visible are the old quayside adjacent to the excavated river dock, and running across the middle of the photo the back wall of what was once the Great Workhouse – the main smelting hall of the early works. This was built adjacent to the canal so that the coal could be off-loaded directly into the smelting hall. To avoid access problems, the canal at this point was covered over to make a tunnel. Boats gained access to the Great Workhouse by portals built into the side of the tunnel, some of which are still extant.
