Middlesbrough town centre as seen from Roseberry Topping. A photo taken during my holiday in Cleveland earlier this year. The pointed black tower in the centre is Middlesbrough Town Hall, with two of its white clock faces showing. The cooling towers in the background are at Billingham ICI chemical works (no longer operated by ICI). Billingham ICI works was apparently the centre for work on Tube Alloys, the British atom bomb project at the start of World War Two. Tube Alloys was merged into the American Manhattan Project in 1943.
