Port Mulgrave Tunnel, What we found inside. I nearly passed out!

We explore a tunnel with breating apparutus on hand as the air is dangerous.

Port Mulgrave Tunnel was opened in 1875 to provide a link between Grinkle Iron stone mine and the port.

In the 1850s Sir Charles Palmer opened Port Mulgrave with ironstone loaded onto small vessels from a wooden jetty. The barges were moved in and out using a paddle steamer.

In 1875 a narrow-gauge railway line was built to the Port. The ironstone wagons from the nearby Grinkle Mine were taken over bridges then through a tunnel under Ridge Lane down a mile long incline on a ropeway powered by a steam engine situated by the east pier, then emerging in the cliff side 30 ft above sea level. The railway wagons were then led onto a gantry, with bunkers on the east harbour wall ready for loading the ironstone directly into ships in the harbour.

The mine and port fell into disuse in the 1930's and parts of the port were destroyed by the British Army in the 1940's to prevent wartime invasion.

We access the tunnel and explore it. The air is contaminated with Methane and Sulphur. This makes it dangerous and proper precautions need to be taken.
