Castle Mills, Edinburgh
Castle Mills were bounded by three roads called Fountain Bridge, Viewforth, Gilmore Park, and by the Union Canal to the south. See map (last photo in series alongside). Gilmore Park (road) crossed the canal by the Leamington Lift Bridge. The 1851 map shows the plot of land occupied by Castle Silk Mills. The rubber business moved out to Newbridge in the 1960s, and the site was largely cleared c.1971 for the construction of a modern brewery, but this has now gone. Some of the NBR office buildings have been saved (see photos), pending re-use (2016). See CANMORE entry for more information.
