Port Mulgrave Harbour
An almost identical picture to the other undated one showing the recent filling of the harbour. I suspect this is deliberate to prevent erosion of what remains of the harbour. There now is a pond with bullrushes in.
Port Mulgrave owes its existence to the ironstone industry. The blocked up mine entrance can still be seen 50' above high water above what remains of the harbour. Tunnelling began in 1854 and work on the harbour had started two years later. By the 1870's new more productive seams were found three miles away at the secluded valley of Easington Beck in Grinkle Park. The only feasible method of transporting the stone out was by sea and so the original tunnel at Port Mulgrave was extended for a further mile to connect to the Grinkle Park mine. Gradually the Port Mulgrave mine itself was abandoned but the harbour continued to be used for Grinkle Park ore until 1917 when a connection was made to the Middlesbrough to Whitby railway owing to the wartime dangers to shipping.
The machinery at the harbour was finally dismantled in 1934 during which the wooden gantry accidentally caught fire. Later the Royal Engineers destroyed the breakwater to prevent German forces using the place for an invasion.
