This photo was taken after WW1. On the right are Colliers at Pelaw Main Staiths with more just 100 yards down river at the Primrose Staith. They are all waiting to fill up with coal. Across the river is the famous Walker Naval Yard. The first Chimney's belong to the Tharsis Sulpher and Copper Works. A bit further downriver are the chimneys of Tennant's Chemical Works. The chimney's were made high to hopefully disperse the dangerous fumes.Tharsis had their own copper mines inland to the region we now call the Costa del Sol.
Today the Siemens Electrical Company factories stand on that land. A perfect place to produce Wind Turbines which are more and more needed.
