Marsden Rock is a rock formation near South Shields, Tyne and Wear, North East England. It is owned by the National Trust. The face of the rock was changed forever when tidal erosion caused the arch to collapse in 1996. Prior to this it was the feature included on most postcards and photographs. The rock is still home to sea bird colonies, with thousands of pairs of Black-legged Kittiwakes, Fulmars, Gulls and Cormorants.
