English: Port Mulgrave mine Port Mulgrave owes its existence to the ironstone industry. The blocked-up mine entrance can still be seen 50 feet 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 1870s 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.
