There is an ancient man-made hollow way cut down into the cliffs to the well-constructed stone quay which is made of large rectangular blocks of stone. The quay projects out from the south-western side of Velvet Beds/Camel Island. It is recorded on Robert Stotes plan of 1768 as a causeway linking the mainland with the island. This part of the island was then called "Stotfold". The quay has been called Roman in local folklore - thought to have been built to transport rock from Marsden Quarry for the building of Arbeia Roman Fort (prehistoric flints have been found on the island but to date no Roman finds), but is more likely to be early post medieval in date, although it was already "ancient" by the time of Stote's map. The quay was a favourite picnic spot in the late Victorian and Edwardian days when parties came to Marsden by boat. The Jarrow Chemical Company may have used the quay in the 1830s for loading keels with limestone for Epsom Salts. There are some iron rings high up on the north-east side of the island, which may be mooring rings or may relate to World War Two activity. Quay is marked as "Old" on the 1st edition Ordnance Survey mapping, so was out of use by 1855. The name Velvet Beds came from the short fine grass which once covered this area, which was springy underfoot. The name Camel Island is more recent, referring to the island's two humps.

Beacons, number unclear, at Man Haven shown on Ordnance Survey first edition 1855. The National Trust information board reads: "This small delightful bay was once used before the building of the Tyne Piers for launching pilot cobles when the sea was too rough to cross the Tyne Bar. Once an active fishing bay, the three semi-redundant boat-houses are all that remains". In 2004 the Arbeia Society recorded a concrete platform with an iron winch at the foot of the pathway from the cliff top. Within the cliff face is a brick arch 3 metres x 3 metres filled in and cemented over. Two parallel sets of stone steps descend to the beach, parallel to a slipway with two remaining timbers and ironwork. Halfway down the path is a concrete platform with an iron winch on it. This is the roof on a pair of huts. There is a steel door 1 metres x 4.5 metres on a concrete base.

Limestone Quarries are marked on the 1st edition Ordnance Survey plan. On the 2nd edition Ordnance Survey plan this site has been engulfed by another quarry (HER ref. 2482), perhaps an expansion of the existing one.

A Lime Kiln is marked here on the 1st edition Ordnance Survey plan along with what appears to be its accompanying quarry. On the 2nd edition Ordnance Survey plan this site has been engulfed by a quarry (HER ref. 2482), suggesting that the kiln was out of use by 1895.
